Hi Jim, What is it about Zune that interests you?
I posted a list of Pros/Cons for it a few days back so if you do a search you should be able to pull it up.
The biggest problem I see right now with the mp3 player market is nobody knows what DRM format to go with. The "Plays4Sure" format the microsoft was pushing (and the Zen uses) is now being dropped by Microsoft for their new Zune format. That means any song you buy for the current generation of Microsoft powered players won't work with the new Zune formatted songs and vice versa. The only company that is left unaffected is Apple as they use their own FairPlay DRM.
