I'm right now in europe, and doing all my math over the internet. well, i'm writing it down on paper but using the internet calculator. I have an ibook from about a year ago. I think that when you put the num lock on, the numbers and such in the corners of the keys should light up with little green lights so that you can actually see where the plus sign and the 5 are. i just though it would be a good thing to have in laptops, do they have it in the new ones? thanks
