Launching products during E3 is maybe not such a good idea. Anyway the rumored PlamOne LifeDrive Mobile Manager is now available for $499 from the PalmOne Store.
Amazon.com, which leaked LifeDrive photos a couple days ago, is not offering the new PDA yet.
The LifeDrive features a 4GB hard-drive, built-in Wi-fi and Bluetooth and 320x480 TFT screen with 16bit colors. It runs on a Intel 416Mhz XScale CPU with Palm OS 5.4 (Garnet). The only other PDA I know that features a 4GB hard-drive is the Sharp Zaurus SC-C3000, which only sells officially in Japan.
