I suppose the major reason I won't go with Palm OS again is that the Treo 300 is such a pain. I've heard that the 600 fixes many of the problems, but it doesn't fix the inherent flaws in Palm OS that make it unable to do two things at once, unstable and incapable of running services, all things Symbian can do.

Anyone else used a Treo 300 and switched to a P800 or P900? Are they more stable?

I really don't like having to reboot my phone...
