I have one. To answer your questions i does have a Zune central that lets you manipulate your tunes. I brought all my music over from a Zen Jukebox no trouble. One thing to note it can only call one computer home. So no syncing with two computers at the house.

As far as warranty mine got wet from my own fault. Sent it in and in 10 days from my door back I had a brand new machine. M$ is awful with Windows support but with hardware they treated me pretty good.

I'd reccomend it over allot of the current offerings.
