After my initial problems, I got a new iPhone from my nearby Apple store and spent several hours using it. My first reaction is that it’s very good, meeting the almost impossible expectations I had for it. Photos are fun and look great, movies are nice and will work great on planes, and the iPod functionality looks good.
The thing that really knocked my socks off was Safari.
I do almost everything in a web app, and even with my blackberry pearl I was stuck with a crippled browser that could only use about half the apps I need. It was a breakthrough over my last device (which was painful for more than 1 or 2 web page views) but I never thought having a full copy of safari on a phone would be so liberating (especially since I only use firefox on my mac).
Usually before I go to bed, I have to sweep through half a dozen sites and apps to make sure everything is on the up and up. I learned that I could do everything on the iPhone, and I could do it from anywhere on earth. This is going to be great for airports and other places where I used to feel bored, trapped, and in dire need of internet access.
So in conclusion, the iPhone is nice from start to finish, but Safari is really the thing that turns it from a phone into a mini-laptop. Once I get more used to two-thumb typing, the last limitations that keep it from feeling like a real computer will be gone.
