Hello Mac world,,, I just bought me a MacBook, about time should'v done that looong time ago, what a great machine! the only mistake that i did is not getting the one with the illuminated keyboard i do use my macbook in the dark, and i wanted to check with you guys, Can i change my keyboard to an illuminated one? is it possible without changing the whole macbook? if so, you think it would cost me my left arm? I tried searching in apple store, but found nothing,,, can anyone help me in this? Thanks!
