Scott Kuhl makes an excellent point about the Zune. For some reason Microsoft did not provide the capability for the Zune to sync with Media Center and have recorded TV automatically placed on their Zune. I can do this on my Windows Mobile device, but in order to do this on the Zune you basically have to hack things a bit. Sync'ing TV should be an easy task that any consumer can do.
Join Scott in his plea to have Media Center integration with the Zune, it just plain makes sense.
