there were tons of smartphones on the market prior to the iphone. i used several of them. mostly windows mobile devices that required a stylus or keypad for input. they had apps stores, web browsers, email, etc. copy and paste, which the iphone lacked at release. from a functionality stance there were many options very much like the iphone available. the interface on the iphone was nicer for most things, and it had a nicer web browser. not a different world of functionality at all, just a bit nicer overall but also with some big trade offs.
