Sony has announced its first true ultrabook, the VAIO T. The design looks much the same as the prototype we saw all the way back at CES, with a 17.8mm-thick brushed metal body that pushes right up against the 18mm limit specified by Intel. The VAIO T comes in 11-inch and 13-inch options, with the latter coming in at 1366 x 768 — Sony makes no mention of the 11-inch model's resolution. Inside there's an Intel Core i3 Sandy Bridge processor — no Ivy Bridge, unfortunately — 4GB RAM, and integrated Intel HD 3000 graphics. Storage comes by way of a solid state drive or a hybrid system that pairs a 320GB hard drive with SSD cache memory for faster bootup times, and Sony predicts nine hours of battery life for the SSD-only model. The VAIO T will be out at some point this month for an unspecified price, which we'd hope would come in some way south of the exorbitantly-priced VAIO Z.
