I used to use it for only that also, but a user-friendly interface makes you more inclined to use other features. My old blackberry had email, but it was clunky and slow. The iPhone is quick and easy to use, so I use it. I used to have all my contacts in my diary, as it was a nightmare to sync contacts from a computer to a Nokia phone, but with the iPhone, it's easy so I use it. Likewise with the calendar. The iPod feature is good too, as I now plug my phone into my car, instead of the iPod. I've found all other PDA's and Blackberries to be cumbersome, slow and not particularly easy to use, which negates their usefulness. The iPhone overcomes this so I use the features. When the video and MMS is added, it'll be even better - not that I use either of them much.
