I've noticed that when I press down on my iPad 2's screen right on the edge below the home button (basically right near the edge between the home button and the dock connector), it feels a little spongy. If I look closely I can see the screen flexing just a tiny bit around that seem. It doesn't feel this way anywhere else around the edge of the screen. Has anyone else noticed this? It doesn't really bother me but I'm trying to determine whether it's a defect.
