I got a 2.4ghz alum macbook back in December and love it. I just started architecture school and they told us to wait on purchasing a computer and every single computer I saw in the school was a Dell! The friendly guy at the Apple store assured me that the new macbooks would run any CAD programs fine with an external monitor. Now I'm not so sure if he was telling the truth or just trying to get a sale! I am sooo dead if I have to get another new computer my Dad would absolutely die! HELP!
