Seems to be a few posts and videos around the internet regarding this issue. Naturally I'm two weeks out of the return window. I'll have to deal with AppleCare on this. Sigh. But yeah, has this happened to anyone else? Was listening to music on my iPod nano. Choose the song I wanted. Went back to pick another song and noticed the sleep/wake button was stuck in the down position and won't respond at all. Lovely.
