This may come to a surprise, but the Zune HD has recently been given a firmware update, upgrading from 4.5(109) to 4.5(114), then minor changes suggest just small bug fixes, but we really don’t know what it does. So, go plug in your precious Zune HD, update your firmware, and let us know if you see any changes.
Update: Dave McLauchlan, has tweeted what the update actually does, it fixes security issues. You can read about what was fixed and the problem here.
