It's the software stupid
It's better in many ways than the desktop version, the way it integrates with your contact's addresses and uses iphone's location services, and also the ability to use multi-gesture to pinch and twist the screen and to tilt the phone (all at once if you like). It's the software like this and the interface which allows for it which makes the iPhone years ahead of the lumbering competition. Of course there will be those who see it has no floppy drive and has lame bluetooth and think that's more important to them, and that's their right.
