Palm OS is better described as "undead, and slowly reviving itself". There are ongoing efforts to port it to diverse new hardware (a couple of new-parts ARM boards, and the Nintendo DS among other targets), an alive community that preserves old software and writes brand new software, and at least one reimplementation project (Pumpkin OS).
