One of the coolest things (at least for a technogeek) of working at Microsoft is getting to check out new stuff before it's released. You get to see the process of new products being built, you get to see the iterations they go through, and sometimes even get to influence how the product works when it is released.
I was recently picked to be one of the beta testers for the new Zune device. First off, having one makes you a rock star around the office. Everyone at Microsoft wants to see it, touch it, have it (obviously!), and understand what makes it so cool. Second, I'm involved in making sure it's ready for the public when it ships later this year. It is really cool...
As far as the Zune itself goes, I can say that it is really cool. I can't say much more than that, but you should definitely stay tuned. In the meantime, check out www.zuneinsider.com.
