So I got the 2.4 macbook last week and exchanged it because the trackpad was loose and the keyboard had a flex on the left side. Anyway I got a new one and everything was perfect on it except for one thing. The top function keys were slanted to left from the esc key to F3 and then to right from F4 to F9 and then back down to left from there to the eject button. I did not want to take it back for just that reason because everything else on it was great, so I took a stiff piece of paper ( a junk mail ad ) and tore off a corner and put it underneath the opposite side of the slant and flexed it back slowly and held it there for 30 seconds or so and it WORKED! I am not so happy it came like that, because of what I paid for it but it was an easy fix and I am completely happy with this notebook.
