Hello everyone! I just ordered a 17" i5 Macbook Pro, my first Apple laptop since my 2002 Titanium PowerBook. I remember that model personally gave me many problems, most of which have probably been fixed or sidestepped in the current unibody notebook models. However, there's one that could theoretically still be a problem. My old PowerBook ended up with a permanently stained grid on the screen that was quite visible. It was caused by the keyboard pressing against the screen, if I recall correctly. Has this problem been solved or will I need to apply a keyboard cover of some sort? Back then I think most people used a mouse pad or cloth. Thanks!
