Honestly, why does everybody keep saying he's doing this the wrong way? It is supported by Apple in a way. While keeping the songs in your iPod rather than your iTunes might be odd, Apple specifically give you the option of allowing you to play songs directly from your iPod. While on someone else's computer, you may want to play music from your iPod, and Apple officially supports that method. I think it's pretty reasonable to want to browse through album art when doing it this way, and would bet Apple will add this functionality in a short while.
