well, i like symmetry, so here is my proposal. macbook: aluminum casing. colors: all current iPod Nano Colors. simple things, matte option, more USB ports etc macbook pro: aluminum casing. colors: aluminum, black aluminum option on 17" more graphic card options, def. should have more than 2 USB ports for a pro machine. option like alienware that has software that can change the color of apple logo/keyboard the macbook/nano line would be the base end spectrum. the macbook pro/classic/touch reflects the higher of both lines i only focused on case design in this, the rest is up to you!
