the new 13inch mbp is about $149 lower than old refurbished 15inch which is $1349 now. It has a better LED screen, and new bettery(some people say that the bettery is not as good as Apple think). Old refurbished 15inch has 9600 GT and ExpressCard port(I do not use SD card) and a bigger screen. I just play some game but I hope I can run COD Modern Warfare2 on it soomthly. Which one is better???Shall I save $149 to buy 13inch??
