Has anyone else noticed that the specs may be incorrect on this product? I want to confirm that this is the latest Macbook, with Leopard installed, but Amazon are not being helpful in providing this information. I don't understand why they'd sell a discontinued product for full price if I can go to Apple and get the new version. I want to buy but can't get the info I need! Has anyone recently bought one who can confirm if it has Leopard installed?
