Ultrabooks stole the show at CES 2012, including one with a unique glass design and one that folds completely back to transform into a tablet. The Dell XPS 13 fits a 13.3-inch panel into a frame 15 percent smaller than the 13-inch MacBook Air. But that wasn't the only story here. Razer showed off a killer gaming rig with a secondary touchscreen touchpad, while Samsung debuted an ultraportable with a 15-inch display. At this year's CES, innovation came in all shapes and sizes.
