The old WinMo was kludgey, but god were there a load of apps for it (ok, no easy app store). I still have my old HTC universal, great phone (if you like phones, laptops and transformers!).
I think apple will become a boutique product again, like they are on the desktop. I can't see anything stopping android now. When my N900 gives up the ghost, I think i'll get an android as well.
