Lie your iPad2 flat on a hard surface and slowly lift it up to about 45 degrees and see that the volume control icon appears and turns the volume down. The control on the 2 is not recessed so it is easily activated when you don't want it to be activated.
I went to the Apple store and commented to a rep and he denied that it is a flaw. Said I was just pressing to hard -- after he did it himself. He still denied it was even happening . Duh. It is and if you hold your 2 at a reading angle leaning it on a desk, it will shut the volume off. Not a good thing. Did no one else experience this ? thanks
