I have no idea, but don't listen to the ipod lovers, they're completely clueless about the Zune. I got a black one, and I love it. Here's why:
1.bigger screen
2.scratch-resistant, durable
3.feels nice in the palm of your hand, really
4.has a nice UI design (way better than ipod)
5.has wi-fi feature so you can send songs & pics to other Zunes
6.has built-in FM tuner
7.you can change the background pic for the whole menu system
8.Zune software has a subscription feature so you can download a lot for 1 price
9.can sync with the Xbox 360
10.you can view videos and some pics in landscape mode (on it’s side) so you just turn it on it’s left side (makes it great for watching videos)
11.you can get 14 day free-trial for Zune Marketplace
12.is something new and has latest technology
About the Best Buy thing, it's just best to call their hotline, or go to Best Buy and talk to a sales representative. It works.
