Since the changes in 9.0.4 and 9.1 don't really affect what I need to do, I've decided to wait until March to just go to OSX. The download for 9.1 is just to big for my tiny 56k modem, and I'm not spending $19.95 plus $5.00 shipping to get the CD via snail mail when it's going to cost around $150.00 to upgrade to OSX anyway. Just my 2 cents. And 9.0.4 works just fine for me. I'm on a G4 and a G4 Cube both with 320 megs. The Cube really does improve the render time. James
