INCREASED PERFORMANCE ON ALL INTEL MACS *drool* 22. (more stuff that i just remembered) Rosetta will most likely see a huge improvement overall. 23. OpenGL improvements.

Podcast Producer I'm not very familiar with OS X Server, so if anyone else has anything to add to that, please do. And to people who say it's too expensive, just look at the improvements. And once more, IT WILL MAKE YOUR INTEL MAC FASTER. YES, FASTER.
