Inflight wifi on Delta via iPhone. Interesting. $8 for the flight. Not cheap, not ridiculous, sort of convenient, but cutting into my nap time.

I have used GoGo on Virgin American a couple of times. It was great - I could keep up with my email traffic and when I landed I didn't have to spend the next few hours at the hotel trying to catch up - instead I could get some food and go to sleep.
