Yahoo upgrades its email for everyone, puts Facebook updates and tweets in your inbox

Yahoo is the latest in a line of would-be champions to try to topple king Gmail from its perch atop the email mountain. The company's newest Mail Beta (no relation to Gmail Beta) was introduced last October, but now its overhauled UI and fresh features are available to all. With the change comes quicker load times, stronger spam filtration, and it lets you send and receive Facebook updates and tweets. It also automatically turns picture and video links into thumbnail previews and handles up to 100MB attachments. These fancy new features are certainly a step in the right direction (even if the purple paintjob isn't), but time will tell if it'll rule the webmail world.

Grace One electric bicycle is ready for purchase, our bank accounts are still preparing (video)

Your average electric bicycle has a basket on the front and a lot of shame in the rear. Not the Grace One. When we first saw it almost two years ago, in the fall of 2009, it looked... well it looked like a pretty kickass bike. Since then the design has been thoroughly refined, the frame redesigned, but still the stacked projector headlamps remain in their aluminum housing in front of the bars. They're a hint at the high-tech nature of this bike, which features integrated Li-ion batteries that charge in about an hour and spin a hub-mounted motor in the rear wheel, giving you a top speed of 30MPH and a range of up to 31 miles -- all for a mere €4,199 ($6,000). If your finances can manage it the bike is available now, but if they can't you'll have to make do with a celebratory video of the thing in action after the break. Word of advice: get those glow sticks cracked and shaken up before you hit play.

HP's Pavilion dv6t and dv7t available with 1080p screens, people who bought three months ago sigh

When HP's Pavilion Quad Edition dv6t and dv7t went on sale three months ago, we couldn't think of too many detractors, but we did take issue with the fact that these 15.6- and 17.3-inch screens maxed out at 1600 x 900 resolution. If you fall into that camp, well, the Powers That Be over at HP heard you -- both machines are now available with 1080p displays, for an extra $150. As before, both come standard with 2GHz quad-core Core i7 processors, AMD Radeon HD 6490M graphics with 1GB of video memory, 4GB of RAM, and 640GB hard drives. HP is also offering free upgrades to 6GB RAM and 750GB hard drive space, though no promises on how long that'll last. Before you get too excited, though, 1080p displays are only an option on these so-called Quad Edition models and the dv6t Select Edition -- meaning, you can't opt for a lower-end dv6 or dv7t and expect to upgrade it. Confusing naming conventions aside, if you're tempted, we suggest you avail yourself of some sweet coupons at the source links.

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.
