I didn't like it and returned this morning. If you aren't using Yahoo music, you are playing too much for the other WiFi abilities. Also, the way you have to select and download the songs as one procedure and then play them as if you loaded them normally is clunky. You should be able to just select and play a streaming song. Rhapsody on the Nokia N800 does this and it rocks.

Other dislikes:
-It also uses a proprietary connector on the unit so you can't just use a standard mini-USB cable--just another funky cable to carryaround if ya need to charge it.
-The scrollwheel is too sensitive.
-Kinda large

Don't get me wrong, it's a nice device and if you want to use Yahoo music, it's the one to get. However, although it works with other PlaysForSure services (eg Napster)--like a normal player via cable, the premium you pay for WiFi is too much.

From the Crutchfield website: "PlaysForSure™ compatibility — plays downloaded music and video files from compatible sources and subscription services, like Napster, Yahoo! Music, and URGE", so not just Yahoo.

it has been reported that it supports WEP, but I'm wondering about WPA. WEP is nearly "open" in my mind.

It appears that much of the dissing of the Zune, particularly the DRM handling, is incorrect according to the indepth review on ExtremeTech at http://www.extremetech.com/article2/0,1697,2061973,00.asp
