Can we request P800/P900 users to post reviews please I have no experience with the Symbian platform, but from what i know, its a nice OS with a relatively small footprint. Kinda like the Palm OS. If your'e used to the windows environment, go Windows Mobile! But windows mobile gadgets (well windows in general )suck up resources bigtime! Thats why windows based PDAs require more memory, faster processors etc..... but IMO, the UI is near excellent!
