Hi, I was waiting for Snow Leopard to arrive and now i will by my next MBP. But i have a few questions: 1. If i order it on the 28th, will it have 10.6 installed already ? 2. Will the refurbished Macs have 10.6 in the next weeks or do they come with the 10.6 CD ? 3. Since the 10.6 has a smaller "footprint", do i win this space when i upgrade from 10.5 ? Does it install the new OS and completely wipe out all files and traces of the old OS ?
