If I order my MacBook Pro tonight, will it arrive pre loaded with Lion or will it still have Snow Leopard installed? In the event that it does have Lion installed, would it be possible to downgrade back to Snow Leopard? Upon reading the initial reviews and opinions of Lion, it seems like it is more trouble than it's worth. I think I'll wait for a couple of stability updates before I go to Lion. EDIT: Also, if I am able to downgrade to Snow Leopard (assuming that my MBP is pre installed with Lion), can I "upgrade" back to Lion by using the restore CD that comes with my MBP?
