Funny thread 🙂
Seriously though, IMO, Palm is past its prime -- it can't compete with Android and iOS, despite it's new "WebOS". Maybe it'll come back in a few years, but I would definitely avoid a Palm.
As far as Android vs iOS, well -- this is an Apple forum, and obviously I think iOS is the best blend of great hardware and software rendering a fantastic UX (user experience).
I have a coworker with a Nexus One (Android) and it has a nice screen, but the new iPhone 4 will top that. The OS is also "choppy" to me compared to the smoothness of iPhone -- even on my 3G.
Hope this helps.
