Having been an Apple user since the early 1980s, I have had a fair amount of experience with the Apple 2, Macintosh 30, various laptops and desktops and now use a MacBook Pro for work and personal.
My wife recently got an iPad 2 and has found it challenging, to say the least. We have worked out most of the kinks but are still stuck with problems with the Camera and Photoboth apps. The camera "shutter" is frozen closed and PhotoBooth just shows the curtain opening repeatedly upon launch.
An interesting point is that our local (small town) Apple approved service bureau just sent my wife back home with the problem, saying her husband (me!) should be able to correct the problems. I can't and am disappointed that this is what a 3-year warranty has come to.
