I've had an iPhone since July 3. After using it for about 2 months I feel that the hype Apple surrounded the phone with in June was NOT enough. This is an amazing piece of hardware/software. The human interface is more than they hyped.
One thought I have is how the interface will expand in the next few years. I routinely hand the phone to people and let them use it. The look on their face is fun to watch. Most people have never held anything like this in their life.
The phone works fine for me, but the other features are impressive. I connect to our wireless network at work and have high speed connections. Many businesses offer high speed wireless connections and I find them easily. The photo album is what blows peoples minds. When you tap on a picture and then expand a part of it, that is beyond most people's dreams.
I know this is verison 1.0 and I usually don't buy something this new in the life cycle, but after playing with one the weekend they rolled out, I decided I had to have one.
