I have an iPod 64gb 5th gen that I got for Christmas and noticed that the Home button makes a slight click when you first touch it. I am NOT talking about the click it makes when you press it. This click can be heard by just lightly tapping your finger on the button. I can best describe it as the outer home button that you touch is sitting slightly above whatever it is connected to on the iPod innards and it has a little in and out "play" before it engages the button. It is not loose or wiggly at all, it just makes this little click. My wife and I both have iPads and it doesn't happen on either one of them. Anyone else experience this? Is it something to be concerned about?
