I get an error when installing, but it still manages to install. As a music player, it seems to work pretty well. I can play songs, manage music, buy something from the iTunes store. It runs very slowly the first time you run it.
What works:
- playing music
- managing music on your computer
- iTunes store
What doesn't work:
- reading/writing to iPod
- closing the app (you have to force quit)
- burning CDs
