Today Fujitsu announced the LifeBook P1500, a convertible tablet that weighs 2.2 pounds and is about the size of a paperback book. Curiously, the tablet runs on Windows XP Pro, rather than Windows XP Tablet Edition, and features a passive touch screen that accepts input from any stylus or even your fingers--no active digitizer pen required. With a 1.2GHz Pentium M processor and 512MB of RAM, will the LifeBook P1500 prove to be the happy middle between a handheld and a laptop? We'll test it soon and let you know. Meanwhile, read more about the Fujitsu LifeBook P1500.
