I bought an iPad 2 refurb from the Apple Online Store. I noticed that when typing on it, it makes a rather loud plasticky tapping noise almost as if I am tapping on an empty plastic shell. Upon looking at the screen closer, it noticeably flexes downwards when pressed lightly. I was under the impression that these screens were glued down tight, not just glued along the bezel edges. My iPhone 4S has a very solid screen and when typing you don't get that annoying plasticky hollow tapping noise. The screen on the iPhone 4S also doesn't flex at all. I know I may sound paranoid, but something just doesn't seem right. I had an iPad 2 refurb before this one that randomly typed on its own, clearly with some sort of screen defect (was exchanged for the one I have now). Despite that defect, when I typed on the screen it barely made any noise at all similar to the iPhone 4S...it felt solidly attached. I'm not sure if this has something to do with it, but my iPad 2 refurb has that stupid bulge on the black bezel where the home button is (as many others have too). If you press down it levels off with the aluminum edge but after 10 mins it pops right back up. It's not nearly as bad as others had, but it's definitely bulging out more than any of the other edges I just wanted to get the opinion of others if they also get that annoying noise while tapping, or if it feels like the screen is solidly glued on and you don't hear much noise at all.
