Hey Bruff,
You may want to use the search feature on this site. There are a few threads already about the Zune here. I bought a Zune myself and so far highly recommend it. Keep in mind there are a few things to consider.
1. Only compatible with XP. Nothing prior, and as of now its not compatible with Vista either.
2. The Zune ONLY has preset EQ settings. Nothing adjustable.
3. Little use for the wireless it has at the moment. (Stressing, at the moment)
4. If you transfer a purchased song wirelessly to another Zune. You can only listen to the song I think 3 times. (no biggy for me, I only transfer music from CD's to mine)
5. The ear buds that come with the Zune suck! (recommend buying the Bose ear buds)
6. Its made by Microsoft!
7. You MUST update the firmware upon installing software on PC. (not a big deal either.
8. Must purchase license for converting DVD's to the Zune. (not expensive)
Even with all the things I have listed here. I love mine! Not had a bit of troubles with it. Also you can demo one, they come pre-loaded with 3 movie clips, probably a dozen or more music videos. And a few dozen pictures.
