It was just last week that we got to take home the Acer Aspire S3, the first Ultrabook to go on sale here in the States. Unfortunately, it doesn't live up to the pillars laid out by Intel: its performance trails similar machines, its battery craps out early and the design, while portable, is too chintzy to make it a bellwether for skinny Windows laptops. Our verdict, in a sentence, was that you'd be better off getting a MacBook Air, or at least considering other Ultrabooks -- namely, ASUS' line of Zenbooks.

In many ways, the UX31 is everything the S3 is not: it has a gorgeous all-metal design and comes standard with an SSD and 1600 x 900 display (not to mention, a case and two bundled adapters). And with a starting price of $1,099, it undercuts the entry-level (and similarly configured) MacBook Air by two hundred bucks. So is this the Ultrabook we've all been waiting for? We suggest pouring yourself a large beverage, settling into a comfy chair and meeting us past the break. We've got a lot to say on the subject.
