With titchy UMPCs like Samsung's Q1 being declared officially rubbish (by us) the door's been left wide open for Sony to breeze in and present a highly portable machine with a proper keyboard. The result is the world's lightest 12-inch laptop.The secret of its meagre paunch is the carbon-fibre shell that stays strong, dissipates heat and, importantly, needs tying down in a summer breeze. It's helped keep the weight down to less than a kilogram, just 898g. The stat's slightly spoiled when you add the DVD burner and extended battery but even then it just tips the scales at a pretty staggering 1.1kg.SturdyInside it houses an averagely powered Intel single-core processor, 512MB of RAM and 80 gig hard drive. Sony also reckons it's sturdy enough to survive being dropped and crushed by up to 120kg, though we won't be testing that out any time soon - at least not deliberately.It’s only slated for release in Japan for now but you can find a friendly importer such as Dynamism to ship one over for you when it comes out.
