I own the 80 GB Zune, and first of all, it was cheaper than the comparable iPod by about 50 bucks. Second, I don't know how your Zune is giving you grief Guitarded, but I've never had any problems at all with mine. It plays well, and syncing it isn't terrible. Using the Zune software is really easy. It has a wider screen, which is fantastic for video. I really need to upgrade to the 120 GB (I acquired TONS of bootlegs since I got this one).
I've used iPods before. iTunes, when I had first downloaded it, made duplicates of each of my music files, doubling the space taken up on my hard drive. As an Apple product, it kept giving me the option to get other Apple products, and every time I click no, it kept offering. So I sold the iPod and got a Creative Zen (which is awesome, but not as good as the Zune). Then the Zune was released, and I jumped on that.
My only complaint for the Zune is the lack of peripherals. Everything is "made for iPod". Damn you, Apple.
