Xperia Play finally lands at O2 UK, available in black or white

It took a while, but that O2-exclusive white Xperia Play is finally with us. Earlier this month, the UK carrier had promised to deliver the Play in June, but evidently things have gone better than expected, as we now see "in stock" signage next to both the black and white models of Sony Ericsson's gaming phone. Pricing is identical for both color variants, starting at "free" when attached to expensive (£34 per month) two-year contracts and peaking at £430 ($702) on pre-pay deals. O2 also throws in a matching multimedia dock plus three bonus games to sweeten the deal. We're guessing that Android 2.3.3 update that Sony Ericsson just rolled out for the Xperia Play might finally have allayed O2's software concerns, which has allowed it to now start selling the device in earnest.

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 available in Australia and Asia, fits Sandy Bridge in under an inch of thickness

The XPS 15z, true to Michael Dell's word, is now with us. Provided "now" is May the 24th in whatever part of the world you happen to live in. Laptop shoppers in Australia, Japan, Hong Kong, and Taiwan -- a group of nations already enjoying the glories of Tuesday -- can now buy the 0.97 inches-thick 15z for prices starting at just under A$1,400. That buys you a Core i5-2410M from Intel (2.3GHz default speed, 2.9GHz with Turbo Boost), a generous 6GB of DDR3 RAM, backlit keyboard, GeForce GT 525M graphics with 2GB of dedicated memory, a 750GB hard drive, and a 64WHr battery. The screen spans 15.6 inches diagonally and offers 1920 x 1080 resolution. Stepping up to A$1,700 gets you a Core i7-2620M (2.7GHz default, 3.4GHz TB) and 8GB of RAM. Juicy specs, we must admit. Now when's midnight coming?

D-Wave One claims mantle of first commercial quantum computer

Whether or not D-Wave has actually built a quantum computer is still a matter of debate (though, a study authored by the company and published in Nature claims to prove its success) but, whatever it is these crafty Canadians have created, you can order one now and start crunching qubits with abandon. The D-Wave One is the first commercially available quantum computer and, while its 128-qubit processor can only handle very specific tasks and is easily outperformed by traditional CPUs, it could represent a revolution in the field of supercomputing. As D-Wave scales up to thousands or tens-of-thousands of qubits, complex number theory problems and advanced cryptographic systems could crumble before the mighty power of quantum annealing... or at least give us faster Google searches. Just out of curiosity, we contacted D-Wave to see how much we'd have to cough up for a quantum desktop of our own, but we've yet to hear back.

Update: Joseph passed along an e-mail from the company with a little more information, including a price: $10,000,000. Yep, ten large, and we're not sure that includes the liquid helium required to keep it cooled.

Samsung Infuse 4G and HP Veer 4G now on sale at AT&T

These two smartphones probably couldn't be any different if they tried -- on the left, we've got the tiny 2.6-inch HP Veer with webOS on board, and on the right is Samsung's Infuse 4G, a giant 4.5-inch Android that costs twice as much on contract. They do have two important things in common, however: they're both available on AT&T right now, and you can read our reviews of each before tossing any money down. Enjoy!
