So, I had a macbook pro 15" but I changed to a toshiba qosmio which is more suitable for gaming. My upgrade was 2.4ghz c2d->2,4ghz core i5 2gb ram ->6gb ram geforce 9600m GT256mb->geforce 330m 1gb. But another difference they have, the toshiba althought it's the same size (at least the screen is the same ) it has a numpad next to my keyboard. I didn't think i would use it, but I realized it's extremely useful! And as I can see, apple doesn't include a numpad even in the 17"mbp!! So I had an idea, they could transform the touchpad to a small touch screen, which with 1 button transforms to a numpad. Or they could even use that screen for other things, like iOS apps, but that's not really useful. A numpad is.
