So, I didn't rush to get one on launch day; But enough people have said good things about it, and it doesn't look like a flop, so today I went up to the Valley Fair Apple Store in Santa Clara at about 4pm.
Walked in, and it was crazy busy, people all huddled around the demo units. I figured they were sold out, but asked an employee, and he said to just go to the checkout. And so now I have an iPhone.
The migration was painless. I ported my existing Cingular/ATT account. When I originally signed up with Cingular, it took 3 hours to activate the phone in a store. With Apple, I did it form home, in 3 minutes, via iTunes. It is about time cell phones stopped sucking.
