I'd be lost without my iphone now,
having internet wherever you go is awesome, can't beat it really.
Have my music/podcasts/videos on there which is great in the gym - much easier than carrying around another ipod/mp3 player all day too
Never really bothered with emails on phones before but got it all set up on the phone and i never check them on the pc now!
Ok the camera isn't great, but it's not that often i use it anyway.
Would definitely take a look at the iphone, especially with the appstore the possibilities are endless! So many new applications all the time, everything you could think of
Definitely wouldn't swap mine for anything else at the moment, as for the touch screen once you get used to it it's great, I bet i could text just as fast on this as i could on a normal phone. Bit weird to start but it's great once you've used it for a bit
