regarding the iphone, you kind of get sucked into apple products once you start simply for the fact that everything syncs so easily with each other why bother with something else and have to re-setup the computers again. i started out with the iphone, then i got a macbook pro, eventually purchasing an apple tv and on a whim purchased the ipad2 and a theater system that works with apple airplay. everything is seamless and it "just works" but as you see, I'm "stuck" in this cycle now with no intentions of getting out.
