Fujitsu on Tuesday introduced two LifeBooks, one palm-sized and the other ultraportable, with features aimed at mobile professionals.

The LifeBook U810 mini weighs 1.5 pounds, has a 5.5-inch light-emitting diode display, and a slim QWERTY keyboard. The device is capable of operating as a standard notebook for accessing e-mail, working on presentations, or surfing the Web. By twisting the screen, however, the U810 becomes a tablet PC with a touch screen for finger or pen input.

For professionals who want a larger, but light, notebook, Fujitsu unveiled the LifeBook T2010, which weighs 3.5 pounds and has a slim 1.3-inch chassis and 12-inch indoor/outdoor LED display. The device, which is also converts to a tablet PC, has a standard battery life of nine hours, Fujitsu said. The PC is powered by an Intel Core 2 Duo U7600 processor, and comes with either Windows Vista Business or Windows XP Tablet PC Edition 2005.

Paul Moore, senior director of mobile product marketing for Fujitsu, said in a statement that the U810 is aimed at mobile workers and "prosumers" who want the mobility of a personal digital assistant but need the features of a notebook. The T2010, on the other hand, is for people who want a lighter version of Fujitsu's LifeBook T4220 convertible notebook.

Both computers comply with the Environmental Protection Agency's latest Energy Star version 4.0 guidelines. For security, both computers come with a fingerprint sensor for encrypting files with a finger swipe. The T2010 also offers an embedded smart-card slot.

The U810 is set for release next month at a starting price of $999. The T2010 is available now, and starts at $1,599.
