I watched it live on my Apple TV.
Mavericks is a stupid name for an OS. No one outside of California will get it...
Mac Pro = I want one!! Not available until fall, and ALL boards, drives, etc, will have to be in external enclosures. Inside will be nothing more than the CPU, RAM, Graphics cards, and flash memory. So any PCI cards, optical drives, hard drives will be additional. Sounds like it could get pricey in a hurry.
