(Daily Tech)-Lenovo has pulled the wraps off its latest ultrabook computer promising a design that is thinner and lighter than its previous ultrabook offerings. The computer has a new innovative trackpad and an enhanced keyboard with refined aesthetics.

The enhanced trackpad is an evolution of the TrackPoint and TouchPad and features a larger, smooth, responsive multi-touch glass surface. The surface is optimized for Windows 8 gestures, click functionality, and has an integrated TrackPoint behavior. The new ThinkPad is the thinnest and lightest T series computer Lenovo has ever made.

“We obsess over the pursuit of perfection – as evidenced by more than 20 years of Lenovo ThinkPad design and engineering accolades. However, perfection cannot be achieved without a key ingredient: customer insight,” said Dilip Bhatia, vice president and general manager, ThinkPad Business Unit. “The ThinkPad T431s is the first device featuring Lenovo’s new design, which represents a comprehensive examination of user experience and input.”

The T431s weighs 3.6 pounds and is 0.82-inches thick. To reach that weight, Lenovo use a carbon fiber top cover and a chassis. The machine uses a third-generation Intel Core processor with Turbo Boost. Graphics are handled by Intel HD graphics (which powers a 1600x900 display) and the computer can be fitted up to 12 GB of RAM.

Other features include a pair of USB 3.0 ports, an integrated fingerprint reader, hardware password manager, and self-encrypting drives (SSDs or traditional HDDS are available). The machine also features an always-on USB port to charge other devices such as smartphones.

The T431s ultrabook will be available starting in April with pricing starting off at $949.
