Derek has had a frustrating time installing the Zune software. I bought a Samsung mp3 player some months ago, but didn't have anywhere near those problems. The software installed without major bumps along the way, although I seem to recall that a couple of things had to be repeated before things worked correctly (I've never installed a Windows program that didn't have a hitch somewhere during installation). None-the-less, the mp3 player works well - it has most of the options Derek is talking about regarding the Zune player. By the way, the Samsung software runs on the same computer which Derek used to install the Zune player a second time.
The main purpose for which I use this player is through the radio in my van (my radio does not have native mp3 capability), and I listen to it when I'm using the excercise bike on miserable days when the weather makes walking for exercise a challenge.
All-in-all, I haven't had the problems Derek ran into with the Zune software.
