I use the iPad2 to view Guitar Tricks lessons, and it works perfectly for me. I have it sitting on my coffee table in the living room, and its a pleasure to do lessons this way.
I will be even happier when you get jam station and tuner working :)
I do have one little suggestion (for Guitar Tricks in general). After vierwing a video, and clicking on Next Lesson, it would be nice if the video would start automatically.
Thank-you for this awesome site.
