I've installed it on 4 computers. None of them are having any problems with it.
The one problem I had, was updating my iPod, but I found the workaround in Apple's forums fairly easily.
But, due to the high number of people having problems, I'm sure we'll see an update in the near future. So far it seems to be about a 50/50 chance of having problems, or no problems at all, just based on websites and forums I've visited that are talking about it.
Personally though, I dig the new version. CoverFlow is great for when I just want to listen to an album, but not sure exactly what I want to listen to. I can just flip through my covers as if I was flipping through my cd rack, and when I come across something, just double click it and it starts playing.
I've been trying to justify in my head $1.99 an episode for TV shows. It's great if you only watch one show. 4 episodes a month = $8 / month. Much better than $30 / month for basic Satellite/Digital Cable. Move up to 4 shows, and you're now at $32 / month. More than 4 shows and you might as well just subscribe to basic service.
I don't watch much TV, but I know I have more than 4 shows I like to watch when I can.
