Acer is pitching its America-bound Aspire V5 Series of ultrathin notebooks at "students and consumers looking for impressive performance, style, and full-featured mobility." That sounds a lot like an Ultrabook, only the Aspire V5 isn't, though it is a slender machine at a mere 0.79 inches and 4.6 pounds for the 14-inch model, and 0.83 inches and 5 pounds for the 15.6-inch build.

Toshiba is one of the many companies using the Computex convention to unveil new Ultrabook models, and is hitting the form factor hard with two new models from the the company's freshly minted Satellite U Series, along with a sweet upgrade to its existing Portégé Z, which will now come equipped with 3rd Generation Intel Core processors (Ivy Bridge). One of the new Ultrabooks -- the Satellite U845W -- also happens to be the world's first to feature a 21:9 cinematic display, Toshiba claims.

Showing up fashionably late to the Ultrabook party is Sony, which is just now unveiling its first Vaio model in Intel's high-performance, ultraportable category of laptops. The Vaio T, as it's called, is a 13.3-inch Ultrabook with a flat brushed aluminum design and magnesium chassis. Sony also unveiled a number of other Vaio notebook models, but let's take a closer look at the Vaio T before moving on.

Having trouble deciding between a notebook or a tablet? Asus invites you to splurge on both by announcing the Taichi at this year's Computex convention. The Taichi isn't unique for the fact that it's a hybrid notebook that pulls double duty as a tablet PC -- there are plenty of other products on the market that pull off the same trick -- but it's unlike anything else out there because it's the first hybrid with a double-sided IPS screen that we're aware of.
