I haven't gotten my hands on a Zune HD yet, but I can say the new software update is working great. In my opinion it beats the crap out of iTunes.

I'm downloading the software now. Hope I like it, and it better not delete all my plays, up to 102k and zune.net acts retarded sometimes.

Awesome I can go buy myself a ZuneHD .... oh wait only available in the US.

Buy it online?

nice the zune hd is gonna wipe its ***** with the new ipod

If you want to get the 4.0 software just go into your settings then to general and look for updates, if you try a manual install from zune.net you will get a hang after install.
