Speaking of the Leopard intro movie, I just spent a few minutes watching the intro movies from all the major releases of OS X. It's fun to see just how much better each version gets. Check them out:
- 10.0-10.2 Cheetah/Puma/Jaguar (on YouTube)
- 10.3 Panther
- 10.4 Tiger
- 10.5 Leopard
I'm pretty sure 10.6 Domestic Shorthair's intro movie will be downloaded directly into your brain. I heard that's a new feature they're working on. That and a tabbed Finder.
