The Lenovo IdeaCentre A720 all-in-one desktop PC we fiddled with at the PC World\/Currys Christmas in July event was running Windows 7, but we're reliably informed that it's really been designed to work best with Windows 8.To begin with, it comes with a 27-inch LED touchscreen so will work nicely with the Metro-style interface and touch abilities of the new operating system. And secondly, it can fold down flat, creating a sort-of Microsoft Surface effect - not the tablet device, but the original Surface, the touch-enabled table.This adds all manner of\u00a0possibilities\u00a0to what initially looks like a normal desktop all-in-one. We've previously seen Settlers of Catan play on a Microsoft Surface table, for example, so can you imagine playing boardgames using a home PC, where players get to virtually move their pieces on a flat board?Because it will run best on Windows 8, we suspect that all manner of touch-enabled apps will be developed that will run across the Lenovo and tablet devices, so there should be no shortage of support. And, even if there is, it's a fully capable desktop computer anyway.Coming with up to an Intel Core i7 (Sandy Bridge) processor, 8GB DDR3 RAM, 1TB hard drive and\u00a0Nvidia GeForce GT630M 2GB discrete graphics it's no slouch for multiple uses. It also features a HDMI output to feed an even larger screen, or an input to add a games console to your desktop if you're using it as your main home screen.An integrated TV tuner helps with that purpose, as does a built-in Blu-ray disc player, and the stereo speakers support\u00a0Dolby Home Theater v4 processing for virtual surround sound. You can even add a 64GB SSD to speed access and boot times, if you don't mind shedding the wonga.Its superslim screen is 1080p Full HD and there's a 720p HD webcam ranged in the frame. Pretty much, it's an all-round entertainment PC. But something tells us that it'll be the cantilevered display that'll get the most attention.Expect to pay around \u00a31,300 when it becomes available in the next month or two.
