For all the mini owners, I have a question regarding the click wheel. On my "big" 20BG iPod, the click wheel is securely fitted in the iPod i.e. when I scroll through songs etc. the wheel doesn't move at all; it's completely static. Now, on my new mini, when I scroll there is a tiny amount of lateral movement in the click wheel (making it less sensitive to the scrolling motion), and I want to know if this is usual for the minis of whether my mini just has a bit of a dodgy click wheel?
