Firmware 4.5 now available for Zune HD

As I've already spoken my piece on the new Zune HD firmware, I'm going to let Microsoft do most of the talking this time (see below). But I will say two things: First, I'm surprised the company got this sucker out so quickly, what with the staunch silence on the actual release date. And second, Zune owners can take advantage of the update right now by firing up the Zune Software and plugging in the device--simple as that.
