To upgrade or not to upgrade ...

I've been hearing a lot of things about instability with iTunes 7 -- that it crashes while downloading songs, and the like. Any truth to this? Anyone using iTunes 7 (on the Mac platform) and having problems? or not having problems? Anybody who upgraded and then had to downgrade?

I would just happily stay with 6, but I've discovered that I can't buy video files without upgrading, and there are some TV episodes that I want to buy. So now I'm trying to decide if I should just be patient and wait for the next update to come out, or take a chance.
