Lenovo's gone official with details on its Ideapad S10 ultra-portable notebook: it'll come with Windows XP pre-installed, measure 9.8 x 7.2 inches, weigh just 2.4-pounds in its lightest configuration, and pack in a LED back-lit 10-inch screen. Powered by Intel Atom N270 and 945 GSE express chipset, the diminutive PC also has some advanced heat-dissipation tech so that your lap and wrists won't get overheated. Interestingly Lenovo notes that "In some countries there will be 9-inch versions," different colors and "Linux preloads"... but doesn't say if those systems will hit the US eventually. Initially then, the S10 will cost you either $399 for a 512MB memory, 80GB HDD model or $450 for a 1GB, 160GB HDD model, and comes in black red or white. Press release info below.
