I think the numpads exist because just about all laptop screens are 16:9 now, which forces the keyboard area to be wider (compared to a 4:3 screen, for example). Without a numpad there would be lots of "dead" space to the right and left of the keyboard, so manufacturers added a numpad to avoid the wasted space. Personally I'd rather have a 4:3 screen and no numpad, but this aspect ratio has ceased to exist.
