OK my mac book was a core duo when I got it now this was in June-August and the core 2 duo came out a short time after that. So if I sent in my macbook to get it's casing replaced cause of discoloring do you think if I asked them to maybe replace the chip to a core 2 duo they would do it? Cause it makes me mad that I got it then a better one comes out for the same price in a short time. I know it's been a long time.
