Microsoft reveals ARM-powered Windows 8 prototypes (eyes-on)

Remember how Microsoft unveiled that whole "Windows 8" thing earlier today? It's back for more: here at Computex 2011 in Taipei, prototype ARM-based Windows 8 slates and smartbooks are coming out of the woodwork. Foxconn, Wistron and Quanta all unveiled early hardware for the new OS, with chips from Qualcomm, Texas Instruments and NVIDIA powering their live tiles -- including NVIDIA's upcoming Kal-El, which got both a tablet and a super-slim prototype notebook to call its own. Dell's also got a XPS development station up on stage, which Microsoft used to demo the UI -- it's bulky and ugly as such things are, but it suggests that Dell's also likely to have a portable Windows 8 machine at some point. For its part, Qualcomm is promising a chip that can instantly wake from sleep, and one of the devices showed that USB host support works fine and dandy. Unfortunately, none of these machines will make their way to market, but it's nice to know that the OEMs care enough to show their solidarity here.

Dell's XPS 15z goes on sale in the US, shiny aluminum is yours from $999

The Dell XPS 15z may not be the gamechanger we'd hoped for, but it's one heck of a Windows PC, and today the aluminum and magnesium alloy machine is on sale in the United States starting at $999. You'll find a total of five different configs available online, with the base model providing a 2.3GHz Core i5-2410M processor, 6GB of DDR3 RAM, NVIDIA GeForce GT525M graphics with 1GB of dedicated video memory, a 500GB 7200RPM hard drive and a slot-loading DVD burner, plus loads of connectivity inside and out -- including dual-band 802.11a/g/n and a pair of USB 3.0 ports. (Whew.) $1,500 ups the ante to a 2.7GHz Core i7 rig with 8GB of RAM, 2GB of VRAM and 750GB of rotating storage, not to mention a nice bright 1080p display. Strangely, there's no solid state option on tap, but you can nab that 300-nit, 1920 x 1080 LCD screen for an additional Benjamin no matter which config you choose. Find all your options at our source link, and while you're at it, why not read our full review?

Update: Aaron wrote in to let us know it's available in the UK too -- starting at £899.

Dell XPS 15z review

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.

Dell XPS 15z unboxing and hands-on

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.

Dell XPS 15z vs. 15-inch MacBook Pro (2011)

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.

	PCMarkVantage	3DMark06	Battery Life

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.

Lenovo IdeaPad U260 review

We mean this with no disrespect to Lenovo, but when you first lay eyes (or hands) on the incredibly attractive IdeaPad U260, it's pretty hard to believe that it was made by the company. Sure, the Chinese laptop manufacturer has always had a certain knack for creating very powerful and well-rounded ultraportables, but "drop-dead gorgeous" isn't exactly how we'd describe systems like the Lenovo IdeaPad U160, Edge 11, or ThinkPad X301. The U260 is indeed a total 180 for the company, and it's one of the most dapper and svelte laptops we've seen in a long time -- there's no question about it, its magnesium-aluminum alloy shell, leather palm rest, and glass touchpad even give the newest MacBook Airs a run for their money. But even better, the 12.5-inch system has the brawn to match that external beauty – its 0.7-inch shell has been injected with a Core i5 ULV processor, 4GB of RAM, and 320GB of storage. At $1,100 (the Core i3 version starts at $999), there's no denying that it's more than enticing, but is the U260 immune to Lenovo's typical ultraportable pain points, including poor battery life and tepid temperatures? We've been lucky enough to spend the last few days with the beautiful machine (yes, we took it on vacation!), so jump down below to find out in our full review!

Lenovo IdeaPad U260

Look and feel

It's obvious by now that we've got a real crush on the U260's bronzish, mocha exterior (it comes in an orange hue as well), and a glance at a few of the pictures in the gallery above makes it very easy to see why. It isn't as minimalistic as some others out there -- say Google's Cr-48 --but the soft-to-the-touch magnesium-aluminum alloy that envelops the system like a book cover gives the entire system a very clean and simplified look. Believe us, it's more than a welcome change from the glossy lids and rounded edges that we've gotten used to on the ThinkPad Edge family. The U260 also feels as high-end as it looks -- it may not have a unibody build, but it has a very rigid construction and that almost-rubbery metal lid not only seems to protect it from scratches, but feels really soft in hand. No, seriously, we've caught ourselves petting this thing a couple of times. Under the lid, the U260 loses its metal coverings, yet has an equally soft faux leather palm rest.

But, it's those aesthetic pieces combined with the U260's very slender design that really makes it turn heads. The system is a uniform 0.7-inches, which means there's no enlarged battery back or slight flare in the front to make it appear uneven, and when you open it up you certainly notice the svelteness of the screen. At 3.4-pounds, the U260 was just slightly heavier than pulling out a netbook at airport security, and it's just the right size and weight to comfortably transport it from the desk to the couch with one hand. Naturally, to maintain its lean body, Lenovo had to nix the DVD drive, but the U260 still houses a good array of ports along its edges. The right side is home to a USB socket and headphone jack, while the left houses USB, Ethernet, HDMI, and VGA ports. Unfortunately, there's no SD card slot, and while there's a place for an ExpressCard card slot, it doesn't open.

Keyboard, touchpad, and screen

There's no doubt that Lenovo knows how to make some of the best keyboards around (see: Thinkpad Edge, ThinkPad T410), but the one on the U260 leaves a bit more to be desired. Don't get us wrong, the squircle shaped, matte keys have a great curve to them and feel as if they were molded for our fingertips, however, the chiclet layout is a bit cramped and doesn't stretch to the edges of the panel. Instead, the right Shift key is noticeably smaller than the one on the left and even the Caps Lock and Tab keys on the left are shrunken. It's not a deal breaker, but it did take us a bit of time to get into the groove of typing this review. Our bigger complaint about the keyboard comes with its lack of a backlight. In fact, it actually seems like oversight to not include a backlit keyboard option on a higher end system like the U260, and we definitely found ourselves wishing it was a feature in a dimly lit airplane cabin.

However, the polished glass touchpad receives our highest stamp of approval. The smooth surface, which feels similar to that a piece of sea glass, was incredibly soft on our index finger and just let the cursor glide along. Additionally, the two dedicated right and left mouse buttons, although slightly mushy, were quite comfortable. While two-finger scrolling worked decently in Word and Chrome, the dedicated scroll strip happens to give you a bit more control.

So, what's it like using the world's first laptop with a 12.5-inch display? To be honest, not that different than using a laptop with a 12.1-inch panel, considering the new screen still has the typical 1366 x 768 resolution. Okay, so it's not exactly great for pixel density, but that doesn't mean we're not seriously impressed with the anti-glare matte display. Yes, that means there's no glossiness or reflections, and yes, it's great! We actually were able to work on the laptop on a bright day without putting up any sort of shade. Too boot, the display is quite bright and the viewing angles are rather decent -- we had no problem sharing the screen in a tight airplane seat with our neighbor. We do have one complaint though -- the screen bezel is certainly glossy and can pick up its fair share of fingerprints.

Performance and battery life

Like the ThinkPad Edge 11, the U260 is available with both Core i3 and i5 ultra-low voltage processors -- Lenovo sent us the highest end configuration with a 1.33GHz Core i5 CPU and 4GB of RAM. As one would expect, the machine handled the brunt of our usual computing tasks, including simultaneously writing this review in Microsoft Word, chatting with friends in Trillian, checking our Twitter feed in TweetDeck, and surfing the web with multiple tabs open in Chrome. Even when we threw a 720p clip into the mix the system was able to keep up.

Speaking of HD content, the machine has no problems with full HD video, but as you can see from its 3DMark scores, it's definitely not a gaming rig. It should be fine for some light mainstream or Flash games, but you're not gonna want to fire up Black Ops on this thing, unless you're cool with playing at very, very low settings. We have to admit it would have been nice to see Lenovo put the U260 up with both discrete graphics and SSD options, though the latter can be accomplished on your own as the entire bottom of the system is removable. Obviously, we didn't test the waters on that with our review unit.

Alienware M11x (Intel Core 2 Duo SU7300)	2689	654 / 5593	4:30

Unfortunately, battery life is the U260's (expected) Achilles heel. On our usual video rundown test, which loops the same standard definition video with brightness set at 65 percent, the integrated 20Whr, four-cell Lithium Polymer battery lasted just two hours and 56 minutes. In regular use -- basically surfing the web and writing this review -- the system ran for about three hours and 20 minutes. Obviously, for a highly mobile system like this, the endurance is pretty terrible, and because there's no way to swap out the battery, you're pretty much stuck dragging the AC adapter with this thing everywhere you go.

Thankfully, there's better news on the heat side of things. Given our experience with the U160, we expected the system to get rather warm, but for the most part the system stayed relatively cool thanks to its "breathable keyboard" and Intel's latest Advanced Cooling technology. While we did notice the bottom right edge getting slightly warm, the vents in the back kept the entire chassis, including the keyboard and touchpad, at room temperature.

Software-wise, Lenovo's actually done a decent job of keeping this one crapware free. However, like the U160 it has a "Smile Dock," which can be launched by clicking on that creepy smile icon on the desktop. You can search Google and check Weatherbug from the dock itself, but other than that it's pretty useless and takes up precious screen real estate. Oovoo and McAfee are also preloaded.

Wrap-up

How much are you willing to sacrifice for love? If you're anything like us, you're absolutely smitten with the U260's metal build, soft leather palm rest, brushed glass touchpad, and the fact that it packs Core i5 power in such a thin shell. But you're also asking yourself one question: can you live with just three to three and a half hours of battery life? For us the answer is sadly a flat no -- in fact, that sort of battery life is simply unacceptable in our book, especially when you consider that equally portable systems like the Toshiba Portege R705 or the new MacBook Airs last at least two hours longer on a charge. It's a sad story of an amazingly attractive and solid performing laptop brought down by a single fatal flaw -- but if you can get past the battery life, nearly everything else about the U260 is almost perfect.
