Taking a page directly from Apple, Microsoft’s Zune player will have a huge assortment of accessories you can buy for it.  You can even see a list of them over at CoolTechZone.  The only problem I can see is that you can’t buy a Zune yet, so why shop for accessories?
“If you thought accessories for Apple’s iPod were getting out of control, wait till Zune hits store shelves. Microsoft is working with a number of partners to develop exclusive accessories for its music player; Belkin is one of the first few to launch a series of new products even though Zune has yet to show up.”
