OK so this is hot. We have wireless capability with the Zune, but that was limited to sharing songs with other Zunes. The new Zunes will allow for wireless sync (when plugged into a power source, dock, etc.). Even more importantly, unlike those option-backdating Apple whores, they aren't sticking it to the little guy. I.e. you don't have to buy a new one to take advantage of this feature. It comes as a firmware upgrade delivered through the Zune software.
The new Zunes feature a $149 4Gig flash model. Here's a hoot - on Amazon if you want my brown Zune, it's $99. $50 more for red.
