Zune is alright
I bought my wife a 120GB Zune and a raft of accessories for it about six months ago.
While she doesn't like it as much as her Creative Zen, she does like it.
The biggest limitation I've seen is that the desktop software to go along with the Zune is fairly weak. Creative's software gave you much more control over what was and was not sync'd.
For the Zune, it seems, if it is in your library, it gets sync'd. Good thing I went for the 120GB version.
There are also some strange quirks like cutting some songs off after 45 seconds or so.
The Zune is a nice little gizmo. It is unfortunate that after all of this time, it *still* needs some polish.
You've got to give Apple credit for that. If there is one thing they excel at, it is polish.
At least I didn't have to install iTunes.
