Asus UX31 vs. UX21... fight! (video)

We'd handled ASUS' UX21 back at Computex, but we'd never gotten up close and personal with its larger brother, the UX31 -- until now. We spotted the 13.3-inch aluminum beaut just chilling at the Ultrabook pavilion at Intel's Developer Forum. With the same 0.67-inch profile as its smaller sibling, that larger footprint means it's naturally a bit heavier (2.9 pounds), yet it's available with the same Core i5 (or optional i7) innards. Expect more when the duo goes on sale later this month, but for now take a peek at our hand-on video after the break.
