Hmm.. 1st gen Nano available for $99 [refurb]

Old 5G iPods will be able to use at least gapless playback - it is an iTunes feature - as well as brightness adjustment and games. Search does not appear to be available on the old 5G or nano; the nano certainly will not get brightness or games. It looks as if the older iPods won’t have the new semi-iconic listing view found in the newer iPods’ menus, either. Any and all of these things could possibly change with a new firmware update, and there are apparently other features that have been quietly added to the old iPods for use by developers. The iPod shuffle won’t get any of these new features.
