I'm not sure if this has been posted yet. In the November issue of Wired there is an ad for a music player which has a very similar wheel on it....it looks almost exactly like the iPod wheel. I thought I had read somewhere that Apple had patented that technology so no other music players could use it. Here is the link:

If it is patented this seems like an issue that needs to be brought up.
