If you're one of the many speculating the release date for Apple's next version of OS X, Leopard, you can tick the other 10 of the remaining 11 business days left on the October calendar because it's finally official: Mac OS 10.5 launches Friday, October 26th at 6.00pm, and may we just say friggin finally. Minimum specs: Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor with 512MB of physical RAM. $129 for a single-user copy or $199 for a 5-user, single-residence family pack. Upgrade price? You're kidding, right... this is Apple.
