I got the same thing on a plane. But my Edge froze on me and I had to remove the battery. The guy beside said "Oh, I didn't know the Ipad had a removeable battery". Then, I explained to him that it was not an iPad but an Edge. He then asked me, why did you have to remove the battery... I said, cause it crashed on me and in order to reset it I had to remove it. He then responded, thats nasty and I said yes it is.... Then, he showed me his Nook...
