I've also had both and the 750 is my all around companion. The iPhone is a cute toy, has a lot going for it but 3rd party apps are very hard to come by and Apple is very coy about upgrades to their baby. Has a beautiful screen, very good quality movie playback and e-mail easy to get to. But there's just something I can't put my finger on that the phone just does not feel right. I guess I was always afraid of dropping it or scratching the screen. Can't enjoy it if you have to handle with kid gloves.
