DaveSt said:I'm not worried about wearing mine out either, that's not really what I was talking about. Any small mechanical device like the home button is a means of failure on the device. I imagine the average MTBF for that button is millions of clicks. Still, there are going to be those unlucky enough to have it fail after 100,000 (or 100) clicks also. It is smart design to remove as many potential modes of failure as possible, and I would have to think that cheap little button is close to #1 on the iPad.
