So wait, you want to buy a Macbook Pro for $600? Or you are saving money and will pay more for it? Simply put, if you're looking for a Macbook Pro for $600, you are going to be looking for a long, LONG time. If you can scrounge up like $1,000-1,100, you might be able to get a little luck with a 15'' 1.83 CD MBP or something like that, but otherwise, old 15'' Powerbooks don't even sell for that low.
