The newest cat to the OS X pack will lauch this Friday at 6:00PM. If you’re one of the first 500 guests to your local Apple Store, Apple will give you a “speical edition” Leopard T-shirt. Though the Apple Retail page is sparse with details, I’m hoping the systems they have setup will all run Leopard as well. I’d really like to test drive Leopard before buying it. I’m leaning towards waiting until 10.5.1 hits, but I’ve been sucked in by the Apple marketing machine before so there’s a chance I’ll walk away with Leopard.
