Seems improbable but it appears to be true: Microsoft's Zune software doesn't work with Microsoft's Windows Vista operating system:
[O]n November 14, Microsoft rolled out the Zune player, which doesn't work with Vista. And so far, the Softies haven't provided any public info (that I've heard/seen) about when the company will introduce a patch or update enabling the Zune to work with Vista.
Yeah, I know. Vista's beta, and I'm sure this incompatibility was mentione somewhere in the documentation, but come on! How hard would it have been to foresee someone trying to install Zune software on their beta copy of Vista? Would some public information about an upgrade plan have killed Microsoft?
Incidentally, has anyone tried installing an iTunes on Vista and syncing an iPod (I'm looking at you, Joey)?
