Apple just refreshed the MacBook specs to max out at 2.2 GHz Intel Core Duo, 4 GB RAM and 250 GB disk. And Leopard, of course. Don't forget to save hundreds of dollars by getting the 1 GB RAM config, then upgrading with third-party RAM from Crucial.com. If you're getting a white one and don't need to burn DVD-Rs, save hundreds more by opting for the 2.0 GHz model, because .2 GHz don't mean a hill of beans in this crazy mixed up world.
