Asus Ultrabook due Tuesday

Asus is expected to announce a range of Ultrabook models, replete with an aluminum chassis and USB 3.0 ports.

Asus is due to release its Ultrabook lineup on Tuesday, as vendor momentum in this new Windows laptop category gains steam.

The Asus Zenbook line is expected to start at under $1,000 and be populated with 11- and 13-inch models ranging up to $1,499.

The UX21 model, for example, will come with an 11.6-inch display, a Core i5 Intel Sandy Bridge processor, and a 128GB solid-state drive. The high-end 13.3-inch UX31 will have a Core i7 chip and 256GB SSD.

Models are also slated to come with beefed-up sound and USB 3.0 ports. The latter feature is not on the $899 Ultrabook announced today by Acer. But don't expect to see USB 3.0 ports on many Ultrabook systems priced below $900 this year. It's too costly to implement in the cheaper models.

Other specs include a weight starting at 2.2 pounds (11.6-inch models), brushed metal surface, display resolutions up to 1,600x900 (13.3-inch models), a SandForce-based SSD, and a card reader.
