I know this has been mentioned previously, but I just "discovered" the four-finger swipe gestures in settings. They are incredibly convenient and save all the button pushing...
Four or five fingers swipe UP and you get the multi-tasking bar
Four or five fingers swipe DOWN and it closes
In an app, four/five finger swipe left or right goes to previous apps or next one
Pinch the screen with all fingers and you get HOME
Wow! Before this, I was using the Assistive Touch in the Accessibility settings. It worked OK, but the little button seemed to be in the way no matter where I slid it to. I've had this iPad2 and iPhone4 for many months and there's still more to learn!
