I have a Zune--one of the small 8GB models. I was totally in love with it until the Marketplace and player software was updated for use with the Zune HD. First, I couldn't get the new software to install, so I couldn't buy music that way (which honestly a big deal). Then I got the software installed and my Zune wouldn't sync anymore. I had to fiddle around with the different driver software versions since customer service is crap. I had to put the old driver back on so it would sync and THEN update to the new version.
I don't know if I'd buy another Zune after that issue, but I probably wouldn't get an iPod either.
