I have to say that I own a zune, and have been both very satisfied with the player but disappointed with the Microsoft support for it.
I too have an older 30gb. I've only used it for audio, but the few pictures I've put on it look fantastic. It sounds great, and I like the new 2.0 firmware navigation. I personally like the software for it much better than the iTunes style navigation, it's quite visual, but beware. You must have Windows XP or Vista, and at least for XP you can't use the 64bit version.
As a plus, you can now buy a iTip to charge it in your car, or if you have a home charger in you house or hotel or wherever.

Interestingly I use my Zune much more than my fiancee uses her iPod.
