I'm not 100% familiar with the Zune, but can I ask a question that I think Worf may appreciate...Regarding file compatibility - can the Zune or Ipod play Flac? Or are you limited to the proprietary Windows Media formats? I assume both the Ipods and Zunes play mp3 at least? Are they both capable of the Windows/Apple lossless formats?

What about video format compatibility? Is there any potential issues there?

I've always found the off-brand units by Sansa to be the better values, but I admit it's been almost 3 years since I last bought one and a lot has changed so I don't know if that is still a fair assessment. I'm probably in the market for one too...my Sansa has suffered perspiration damage - they don't build these things for long runs in July!
