I'll really only need GB and iPhoto, and mayybe iMovie. I guess iMovie 3 is better for my comp than iMovie 6, though.. iPhoto has become faster and faster for each new version, but this version might be different.. I'd really like to have Events, though. I have a library of soon-to-be 5000 pictures, and finding stuff is hard..
The first GarageBand was way too slow on a 700MHz G4. The second one was better, so I'm sort of hoping '08 will work even better.
