Acer has announced two new Windows 8 Ultrabooks at Computex this week. Known as the Aspire S7 series, both systems feature all-aluminum bodies with full HD touch screens in what the company calls the "thinnest and smallest" HD Ultrabook, although detailed measurements outside of it being 12mm thick (13-inch model) were not on hand at the show.

Systems will be available with 11.6-inch and 13.3-inch displays. The smaller unit features up to 9 hours of battery life and includes a light-sensing keyboard that automatically adjusts the backlight of the keyboard based on ambient conditions. The system also features what Acer calls a Twin Air cooling system to keep overall temperatures down and provide better thermal comfort, presumably when resting the system in your lap.

The larger 13.3-inch system is said to provide up to 12 hours of juice and features the same auto-backlit keyboard and Twin Air cooling system. This premium model also offers a glossy sculptured glass cover which may or may not be a fingerprint magnet.

Engadget spent a few minutes with the system and noted that it wasn't as reflective as a typical plastic lid. The display on both systems is able to fold back to a full 180 degrees in order to lie flat. Additional information from Techzek says that Acer will be shipping systems with Intel iCore series processors (Ivy Bridge), although exact chip information wasn't provided.

No further specs or pricing information was provided at Computex. It will be another four months or so before these systems are released as that is when Windows 8 is expected to launch.
