I'd like to see the sort of moves suggested by CrashAndDie with one exception: I don;t want a separate 'business' maemo and leisure maemo. I want one device that will do it all. One device that will be my work unit for connecting to groupwise, email exchange etc, and my fun device with games, videos and music, my connected device with twitter, tumblr and LJ, and my 'me-time' device with books and a Bible.

As I see the market right now, maemo is the OS most likely to be able to deliver that in 5 years time.
