It's been awhile since I went to the Apple Store online. There's only one current MacBook model now, no aluminum model? I am trying to decide on either a MacBook aluminum, which now appears to only be available in a refurb or a MacBook Pro 13.3 for my son that is graduating from college. I'm not sure he really needs the Pro model, so just kinda thinking that I could save a few dollars. Can anyone help me with this decision?
