In the refurbished section of the apple website, there is a macbook 2.4 that is running for 1,299. The only difference is the 1200 x 800 mega pixels. The brand new ones have 1280 x 800. Is that even a noticeable difference? Does that mean the screen is broken? Thanks for any comments im lookin to purchase a macbook 2.4 aluminum joint but im a little concernced..
