You can send pics from the iPhone to email, but I don't believe to other phones.
It depends on what you want in a phone. For me, the tactile experience of the iPhone is 2nd to none. It just flows - The way it feels in your hand, the way you scroll, the ipod, phone, email, surfing. The new App store lets you download apps right to your phone, many free, most a couple of bucks.
On the down side, no copy paste, no web videos (can do Youtube vids), the keyboard takes getting used to, and it's a little buggy. In my area ATT works well, but may not in your area.
I had a Palm Treo 650 before the iPhone, and some basic functions it did better. But for the coolness factor there is no comparison.
I went into the ATT store and picked one up (they have them live and connected) and played with it for about 1 hr. I emailed, called people, texted, put things in the calendar, etc. By the time I was finished I knew I'd get one.
