Dell XPS 15z review

0 comments
For years, Dell's been teasing supermodel-thin laptops, each one flawed out of the gate: too pricey, too underpowered, and with underwhelming battery life. This time, Dell told us we'd get something different: a laptop without compromise. Recently, Round Rock killed off the Adamo and nixed the XPS 14, and then rumors started to spin -- a spiritual successor would be the slimmest 15.6-inch notebook we'd ever seen, be crafted from "special materials" and yet cost less than $1,000. Dell even stated that it would have an "innovative new form factor" of some sort.

The company neglected to mention it would look like a MacBook Pro.

This is the Dell XPS 15z, and we're sorry to say it's not a thin-and-light -- it's actually a few hairs thicker than a 15-inch MacBook Pro, wider, and at 5.54 pounds, it weighs practically the same. It is, however, constructed of aluminum and magnesium alloy and carries some pretty peppy silicon inside, and the base model really does ring up at $999. That's a pretty low price to garner comparisons to Apple's flagship, and yet here we are. Has Dell set a new bar for the notebook PC market? Find out after the break.


Design

Clean lines, smooth curves, and vast expanses of beautifully textured metal, cool to the touch -- the MacBook Pro has captivated Apple fans for years, and there's no doubt Dell's trying to capture much of the same charm. From the aluminum chassis to the placement of the speakers, DVD drives and majority of ports... heck, even the tiny arrow key bars on the backlit keyboard and feet on the bottom of the chassis are cribbed from Apple's product.


It's honestly difficult to find anything on the entire notebook that feels wholly original, though there are a few Dell tweaks -- the speakers and vents have the same pattern as those on the Inspiron Duo, and last year's XPS lineup contributed its distinctive hinged screen, which lies flat on top of the notebook rather than forming a traditional clamshell case. You'll also find plenty of chrome trim, ringing both the chassis and the oversized touchpad.

But let's get this out of the way right now: though the XPS 15z most definitely looks like a MacBook Pro and sports similar materials, you'll wind up disappointed if you're expecting the same exacting attention to detail. You're looking at an aluminum and magnesium alloy sandwich here, not a unibody frame, and much of that metal is thin enough to flex under a little bit of pressure. While typing, we noticed that if we put a little weight on the keyboard, we'd oh-so-slightly squish the whole frame, not enough to make a lasting impression, but enough to audibly restrict airflow to the system fan. And -- at least in our pre-production model -- that aforementioned chrome trim had rough edges that slightly chafed our wrists. We also have to laugh at Dell's decision to place all the I/O ports in a row on the left-hand side, just like Apple's rig, as we've often felt Cupertino sacrificed function for form in so doing.

Still, it's a very attractive machine...

Display / Speakers / Keyboard / Trackpad

...and it looks even better when you lift the lid to find this optional 300-nit 1920 x 1080 screen. Yes, while Apple fans still have to settle for a 1680 x 1050 pixel picture in a 15-inch chassis, an extra $150 buys the XPS 15z a full 1080p display, allowing for high-res movies, games, and wonderfully roomy split-screen multitasking. It's a pretty bright, beautiful picture on this particular screen, too, and though the contrast isn't quite as high as we'd like, Dell's software will automatically adjust the backlight to give you the best out of your blacks and whites. It's also quite glossy, unfortunately, and viewing angles are pretty terrible here, as the picture becomes far less vibrant if you shift your head even slightly to the left or right.

That's a shame, considering that the XPS 15z's speakers sound like they're designed to be shared. We're not sure what kind of drivers lie beneath those patterned grilles, but they sure are loud, and create a wide soundstage perfect for movies and games even though they have little bass to speak of. They're also a little shrill at maximum volume, but they're still a cut above most laptop speakers we've used.

Dell's been on a chiclet keyboard bent as of late -- following the global trend -- and while opinions differ regarding whether floating islands or distinct grids make for better typing, we can't complain about the sea of squares on the XPS 15z. As we've already alluded to, Mac users will find themselves completely at home with the layout, and the keys themselves are fairly friendly, too -- rounded, comfortable, slightly convex little squares and rectangles with a smooth, rubbery action and nice big tactile guides on the home row. There's no dedicated numpad here, a bit of a shame considering that there's definitely space, but we suppose some things have to be sacrificed for symmetry and a pair of speakers loud enough to fill the room.

Speaking of symmetry, you'll find the XPS 15z trackpad front and center in the experience, and we're happy to say it's a fairly pleasant one -- the oversized Cypress pad is quick, responsive and accurate for single-finger input, and comes with a pair of large, clicky and satisfying mouse buttons. What's more, it does two, three and four-finger multitouch gestures, though you'll note we didn't include them in the "quick, responsive and accurate" part. Some work amazingly well (swipe four fingers sideways to engage Windows Flip 3D, then drag one to flip through your open apps) and some fail miserably (far too often, the trackpad detected a pinch-to-zoom motion when we intended to do two-finger scrolling). You can tailor gestures at whim in the Cypress settings page, but we were surprised to find that our changes didn't stick. The next time we rebooted the machine, those problematic default settings were back again.

Did we mention that the entire palmrest is made of magnesium alloy, including those speaker grilles? The whole surface you interact with is smooth, durable, and dirt-resistant too, as the only way we were able to leave a visible fingerprint was by touching the glossy screen itself. We should note, however, that the metallic surface is a double-edged sword here. We noticed that our fingers were getting mighty toasty during a benchmark, as if the computer was venting hot air right right onto our skin, and during an intensive session of Bulletstorm, we found the magnesium spacers between the crucial WASD keys was burning hot to the touch. It seems that Dell may have put some important silicon right underneath those keys, so you may want an external keyboard at your next LAN party.

Performance and battery life

Yes, you heard us right, a LAN -- the XPS 15z may not be a gaming rig per se, but for $999 there's more than enough power under the hood for a few frag sessions. Even the base model is loaded with a dual-core 2.3GHz Intel Core i5-2410M processor, switchable NVIDIA GeForce GT525M graphics with 1GB of memory, and 6GB of DDR3 RAM, a 7200RPM hard drive and loads of high-end connectivity. You'll find a gigabit Ethernet jack keeping the power socket company around back, two USB 3.0 ports on the left-hand side, along with one eSATA / USB 2.0 combo port, one Mini DisplayPort, and an HDMI 1.4 jack, a pair of 3.5mm headphone and microphone jacks on the right, and a dual-band Intel 802.11a/g/n WiFi radio inside.

What can all that do in practice? Well, we're actually not quite sure about those particular specs, since we actually received the 2.7GHz Core i7-2620M version with 2GB of dedicated graphics memory and 8GB of RAM. That kind of rig will run you $1,534, but it'll also do some potent processing.

Case in point: We launched our Chrome browser with a dozen Engadget tabs, started playing a DVD copy of Hitch, fired up a 720p windowed version of Batman: Arkham Asylum, and started opening windowed 1080p movie trailers for The Dark Knight all at the same time... and it was only after the third concurrent trailer on top of our perfectly playable game session and DVD movie that we started noticing a little slowdown. In other words, multitasking is a go, and in case you're wondering, Windows told us that particular load still only used 80 percent of our available CPU cycles.

The XPS 15z also pulled its weight in a dedicated gaming scenario, playing that same Batman: Arkham Asylum at 1080p with all settings maxed save AA, and managed to deliver 30FPS on average. Similarly, Call of Duty 4: Modern Warfare gave us around 40FPS with 4xAA and all settings maxed. Bulletstorm proved pretty taxing, though: we had to drop resolution to 1366 x 768 and reduce details to medium to make that game playable. If you're aching for some more theoretical benchmarks, our XPS 15z pulled scores of E1511, P894 and X282 in 3DMark11, and earned 8023 PCMarks in PCMark Vantage and 7,317 in 3DMark06. By the by, boot times weren't amazing, but they're certainly not bad, as we clocked 40 seconds for the machine to load into Windows, or about a minute for the machine to finish loading startup programs and be completely ready for use.

Notes: the higher the score the better. For 3DMark06, the first number reflects score with GPU off, the second with it on.

We'd mentioned that Dell's previous attempts at premium systems failed price, power and battery life tests. With the XPS 15z, well... two out of three ain't bad. Despite the fact that the NVIDIA Optimus GPU turns off when not fully taxed (powering the laptop's display with integrated Intel HD 3000 Graphics instead), we weren't able to get much more than three and a half hours of regular use out of our review unit. Turning to our standard battery drain test (where we loop a standard-definition video with the screen at roughly 65 percent brightness, and with WiFi on), we saw much the same thing -- 3 hours, 41 minutes of use from the sealed 8-cell, 2.6Ah battery. It occurred to us that perhaps Optimus wasn't actually switching off the discrete GPU at the most appropriate intervals, and sure enough, we were able to eke out a little more runtime by completely disabling it, but you're still looking at 4 hours, 26 minutes of use. That's not bad, all things considered, but it's a good sight worse than the 8 hours of life that Dell's advertising here, and if the company wants to make a dent in the MacBook Pro's armor, it'll have to do better than that.

Software and Stage UI

The XPS 15z comes with the usual array of mostly unobtrusive bloatware, including a trial subscription to Norton Antivirus, the token copies of Microsoft Office Starter and Roxio for your disc burning needs -- but there is one thing out of the ordinary, and that's Dell's Stage UI. That's right -- the company's divorced its custom touchscreen interface from the Inspiron Duo and Streak, and turned it into a launcher bar that sits at the bottom of your desktop. There's no need to fear for your Windows 7 taskbar, though, as Stage buttons are just shortcuts to quickly launch your favorite multimedia, and the gallery, audio, video and podcast players are actually rather good-looking in our honest opinion. If you don't care for the bloat, it's all quickly uninstalled. Everybody wins.

Wrap-up

These two laptops are not equals, but they never had to be -- for hundreds upon hundreds of dollars less than the Mac competition, Dell's unleashed an attractive, powerful and definitely desirable Windows PC. It's perhaps desirable enough to woo buyers who prefer Windows but love the Mac aesthetic. We suspect that's Dell's plan here, because while we really appreciate the XPS 15z's metal construction and choice parts, it hasn't really changed the game.

It's no lighter, thinner or particularly better armed than the competition, and when it tried to borrow the MacBook Pro's flair, it picked up some of Apple's failings along the way. We're not just talking about the inability to having chunky USB peripherals plugged in at the same time, but rather the ability to configure and upgrade the machine. While that dual-core Core i7 processor, GeForce GT525M GPU, 8-cell battery and DVD drive are nice to have, that's the best you'll get here -- even though Dell's slightly chunkier XPS 15 is configurable with quad-core processors, faster video options and a Blu-ray drive to deliver extra value to that 1080p screen.

When Dell tells you that the XPS 15z has no compromises, that's not quite the case -- it's a solid choice at this price point, but corners were cut to get here.

Apple patent application reveals an LCD with switchable, privacy-protecting viewing angles

0 comments
Don't you hate it when the guy next to you on the subway is looking over your shoulder, watching you screw up in Fruit Ninja? Well, Apple could have predicted your discomfort -- back in November 2009, before the iPad was anything more than a unicorn, the company applied for a patent on an LCD display with adjustable viewing angles, explicitly designed to "shield the display away from unintended viewers." According to the filing, the display would include steering modules made of liquid crystal material, which aim the so-called scattering modules that sit on top of them. The top layer then redirects the light, making it possible to narrow down and alter the viewing angle. The patent specifically calls out cellphones and laptops, paving the way for discreet displays on MacBooks and iPhones, though the broad phrase "other portable electronic devices" leaves plenty of room for iPads and iPod Touches. No word, of course, on when or if Apple will secure this patent and if so, what devices might incorporate such screens. We may just be seeing this concept go public now, but it seems consumers could use this even more today than they did back in the fall of '09, when all they had to worry about was a stranger squinting at their 3GS' 3.5-inch screen.

MacBook Pro review (early 2011)

0 comments
Apple might say we're in the post-PC era, but hey -- turns out they still make Macs in Cupertino, and the new MacBook Pro is actually one of the more aggressive refreshes in the machine's history. Not only has it been less than a year since the last MacBook Pro spec bump, but our 15-inch review unit is actually the first Sandy Bridge system we've received from any manufacturer. And it's not just the CPU that's new: Apple's also launching the new Thunderbolt high-speed interconnect, and there's been a big switch to an AMD Radeon HD 6750M GPU paired with Intel's integrated HD Graphics 3000, an arrangement that should offer both solid graphics performance and great battery life. That's a lot of new parts in a familiar case -- but do they add up to something more than just a speed bump? Read on for our full review!


Look and feel

It's been nearly three years since the MacBook Pro last had a significant design change, so you'll need some eagle eyes to tell these new models apart from its predecessors. Seriously, Thunderbolt even uses the Mini DisplayPort connector, so the only distinguishing characteristics are the lightning-strike Thunderbolt icon on the port row and a subtle new texture to the aluminum lid. Oh, and the SD slot is now SDXC. Almost everything else is exactly the same: the still-best-in-class keyboard and glass multitouch trackpad, the standard glossy display, the ports, the sealed-in battery, you name it.

That's both good and bad, of course: Apple's competitors have only recently gained any ground on the MacBook Pro's unibody build quality and stiffness, but would it really kill anyone to throw in a couple extra USB ports? And maybe space them out enough to allow for both a thumb drive or wireless card and another device without an extension cable? That would be cool. And while we're at it, we'd also love that optional higher-res 1680 x 1050 display to come standard -- in matte, if possible. We will not even begin to lament the lack of a Blu-ray option; down that road lies only the aching pain of desire forever unfulfilled.

To sum this up: it looks and feels exactly like a MacBook Pro. It's still the industry standard in terms of design and quality, but after three years competitors like the HP Envy 14 have started knocking on the door, and we'd like to see the best get even better the next time around.

Performance, graphics, and battery life

No two ways about this: the new MacBook Pro is the fastest laptop we've ever tested, hands-down. We were sent the stock $2,199 15-inch MacBook Pro, and its 2.2GHz quad-core Core i7-2720QM, 4GB of RAM, and AMD Radeon HD 6750M graphics with 1GB of dedicated GDDR5 RAM turned in numbers exceeding any Mac we've ever had in the labs. In fact, the raw CPU score is so high you'd have to step to a Mac Pro and Xeon processors to get anything faster, as far as we can tell. (That'll obviously change when Apple bumps the iMac line to Sandy Bridge.)

Notes: battery life on all machines but the Air calculated using our standard video rundown test; Air was a usage test

Let's talk about those graphics scores for a moment. While the Radeon HD 6750M performed admirably when active, it also seemed to run a little hot -- yes, we got between 80 and 130fps running around in Half-Life 2: Episode 2 at native res, but the fan kicked in as soon as we launched the game, and it stayed on loudly the entire time, even as the case got noticeably warm around the hinge. It's obviously a capable GPU, but it's a good thing the system automatically switches to the integrated Intel HD Graphics 3000 when it's not needed -- there's a serious decrease in heat and power usage.

Unfortunately, reduced heat and power usage comes at the expense of raw capability. Intel's integrated graphics have never been much to write home about, and while HD Graphics 3000 is an improvement, it's still pretty slow. Apple told us Intel integrated graphics performance should equal or exceed the previous Pro's integrated NVIDIA GeForce 320M, but we found it to be slightly slower at every turn, although not enough so to be dramatically noticeable. It's not a huge problem on the 15- and 17-inch Pros, since you can fall back on that Radeon, but we wouldn't try to do more than average HD media playback or casual gaming on the entirely-Intel 13-inch model.

On a happier note, we set up Boot Camp and ran benchmarks in Windows 7 to provide some more context to our numbers, and the MacBook Pro crushed those tests as well -- the VAIO Z only got a better PCMarkVantage score because of its fast SSD, and the Envy 17 just barely pulled out better graphics performance. (You can configure the MBP with a 128GB SSD for $100 extra, which should probably be standard over the pokey 5,400RPM hard drive.) Playing a little Batman: Arkham Asylum while booted in Windows netted a smooth 60fps at native resolution while meandering about, with a dip to 55fps during fights.

Dell XPS 14 (Core i5-460M, NVIDIA 420M) 5796 1955 / 6827
Notes: For 3DMark06, the first number reflects score with the discrete GPU off (if possible), the second with it on.

Needless to say, we had no problems getting through a workday on the new MBP -- we generally juggle Firefox, Chrome, email, a couple chat clients, and various image and video editing tasks on and off throughout a day, and things never felt sluggish or laggy at all. Used this way, we also managed to get around seven hours of battery life, which is pretty impressive -- we imagine things would have dipped had we fired up the Radeon more often, but in day-to-day usage the Intel graphics did just fine.

And fair kudos to Apple: with the MacBook Air, the company switched to a new battery test that automates browsing popular sites over WiFi at standard brightness, which generates a more accurate number, but also means the new MBP actually is rated lower than the outgoing model using the same battery. That's a solidly consumer-friendly move, and one we definitely wish more PC manufacturers would make as well.

FaceTime HD

Apple's been chugging along with VGA webcams on their machines for so long we were actually shocked when we found out the new MacBook Pro has an upgraded 720p FaceTime HD camera in the lid. Image quality is obviously improved from the previous generation, and we noticed a slightly cooler cast. We'd love some fine-grained image controls at the system level for this camera -- even just white balance and exposure sliders would go a long, long way.

Although FaceTime now supports HD calling, Photo Booth weirdly hasn't been updated and still takes VGA shots. Same with Skype, which only supports sending VGA video on OS X right now -- we'd imagine an HD-ready update is a much higher priority now, though.

Thunderbolt

There's just not much to say about Thunderbolt right now -- yes, the port is there, but there aren't any peripherals that use the new 10Gbps dual-channel interconnect just yet. LaCie's announced a dual-SSD Little Big Disk and Promise has announced a Pegasus RAID, but neither of those are shipping yet. Of course, Thunderbolt also carries Mini DisplayPort video, and we were able to drive an external 24-inch monitor without any issues, using an existing Mini DisplayPort-to-DVI adapter. We'll note once again that this marks the first time we can remember Apple switching standards without switching connectors -- a watershed moment in the history of dongle purchasing.

In any event, we're marking Thunderbolt as an incomplete right now -- until there are peripherals to support it, it might as well just be a Mini DisplayPort. That'll change soon, though, and we'll revisit the subject when that happens.

Wrap-up

Apple's forging headlong into its next era with the iPad and iPhone, and it almost seems like the company's forgotten about its Macs at times -- note that this MacBook Pro arrived in somewhat unheralded fashion just few days before the iPad 2. But the new Pro is something of a wolf in sheep's clothing: although it's perfectly disguised as the previous MacBook Pro, there's no mistaking its raw, visceral speed once you start using it. It's twice as fast as the outgoing model, 2.5 times as fast as the model before that, and almost five times faster than the 11.6-inch MacBook Air... all while getting the same seven-hour battery life in the real world. It's hard to say anything bad about that.

Of course, there's no getting around the fact that the MacBook Pro is still incredibly expensive and omits what should be no-brainer features -- $2,199 for two USB ports and no Blu-ray drive? -- but those are tradeoffs and prices professional Mac users have long become used to, just like this particular MacBook Pro design itself. Something tells us the next revision of the MacBook Pro will offer a more radical external redesign to go along with Lion, but that's a long ways off -- until then, this MacBook Pro represents the best blend of power, portability, and battery life we've come across to date. We'll see how the PC world responds with its Sandy Bridge systems soon enough.

Apple's MacBook Air duo to receive Sandy Bridge and Thunderbolt upgrade in June or July?

0 comments
We've already seen Intel's Sandy Bridge processors and Thunderbolt reinvigorating the MacBook Pro line, so it's only logical for the MacBook Airs to eventually follow suit -- presumably they'll pick up Sandy Bridge's 17W mobile processors to match the current 10W and 17W Core 2 Duos. So when can we expect this to happen? Well, according to DigiTimes' sources within the supply chain, Apple may receive shipment of the refreshed Airs in late May ahead of a June or July launch -- this echoes earlier reports from Apple Insider and CNET that cited the same time frame. Additionally, DigiTimes says Quanta will continue to assemble Apple's ultra-portable laptops, with Simplo Technology and Dynapack supplying the battery packs. As always, we shall remain open-minded about such rumors, but you'll know the real deal as soon as we do within the next couple of months or so.

How would you change Apple's Thunderbolt-equipped MacBook Pro?

0 comments
Same 'ole, same 'ole? There's no doubt that Apple's newest MacBook Pro looks awfully similar to the models that have come before it, but the engineers in Cupertino still managed to shake a few things up on the early 2011 model. Aside from throwing an AMD GPU under the hood, pairing that with Intel's integrated HD 3000 chipset and implementing Sandy Bridge, there's also an entirely new I/O port: Thunderbolt. But was that really enough? For those of you who couldn't escape the upgrade bug, we're curious to know if you've been satisfied with the upgrade. If you had control of things, what would you change? Add a few more USB ports? Insist that native USB 3.0 support be added? Throw in a Blu-ray drive? Maybe add a couple of palm rest stickers? Toss your ideas out in comments below -- but let's keep it civil down there, cool?

Apple patent application shows keyboard that doesn't require contact, blows air

0 comments

We've been generally satisfied with the chiclet-style keyboards that have become omnipresent in laptops and Apple's latest generation of desktop keyboards, but Cupertino feels that these thinner, lower-profile input devices limit tactile feedback. A patent application from Apple, filed in 2009 but only now revealed, aims to improve the user experience by "expelling air from the input device proximate the key when user selection is imminent." That's right -- your keyboard could blow on your fingertips as you blow our minds in the comments. Another solution in the patent would function like a vacuum to pull keys away when a proximity sensor detects that you're about to type, providing simulated feedback. If this concept takes off in the future, your next MacBook Air could really live up to its name.
