Engadget - It's incredible to think that when CES 2012 kicked off back in January we had only reviewed five Ultrabooks. Yep, five. Enough to count on one hand. Even weirder, we still hadn't seen that many by the time we wrapped our coverage of the show. Sure, a few companies teased ultraportables they planned to release later in the year, but these only represented a slice of the 100-plus models slated to launch in 2012. And that didn't even include all the Ultrabook imposters! Ever hear of Sleekbooks? Ultrathins? Whoever said PCs are dead clearly doesn't have to review them for a living.
