So which iPad (storage, 3G or not) did you get?
I had lots of fun just playing with the machine when I first got it. Get all the aviation apps and try them out for yourself. They're free for a month.
I liked getting them at the same time (Foreflight and WingX Pro at the time, Garmin Pilot wasn't around) and trying them in parallel, to see which one I liked best. I do know others that prefer to go through them one at a time to better concentrate on each one.
