Since I dinged Microsoft for its lack of Windows Vista compatibility when the company launched its Zune MP3 player on November 14, it's only fair that I note that the Zune is officially Vista-compatible, as of today.
It doesn't sound like Microsoft is making things easy on Zune customers, however. Microsoft has released both updated Zune software for PCs and updated Zune firmware. From early reports, it sounds like the firmware update is not so smooth.
And if you were holding your breath in anticipation of Microsoft to release any new features (like Wifi video sharing) via the updates, you can exhale. THe updates released on December 19 are all about plumbing only.
