I don't know anything about Zune, but the biggest problem I've had with iPod is when they upgrade their software it’s always resulted in me losing my entire library; then I have to call them to get it fixed. This last time around they had a software upgrade for both iTunes and the iPod at the same time. They had no advisories about the order how to do things, so I upgraded my iPod first; which resulted in my library on my iPod being dumped and not syncing up with iTunes. Then I tried to do a restore and it wouldn’t work. Still an empty library. I ended having to call Apple and they said I had to upgrade iTunes first then the iPod because the newer version of the iPod wasn’t compatible with the older version of iTunes. I have never seen any backwards compatible problem like this before. They admitted they are trying to resolve the problem, but I have to tell you this seems to happen every time they come out with an upgrade. The other part of this is, if I hadn’t bought the extended service I would have had to pay for the call to Apple.
Other than that I think it’s a decent player.
