Acer’s first Ultrabook, the Aspire S5, also happens to be one of the first of what will certainly be a tidal wave of Ultrabooks announced at CES this year. It’s just 15mm thick at its largest point, and weighs in at less than 3 pounds. But it’s probably only going to hold that “world’s thinnest” title for a few hours until the Ultrabook floodgates open. Tick tock.
