does anyone ever actually ONLY game on their computer? ![Tongue :P](https://cdn.geekhack.org/Smileys/solosmileys/tongue.gif)
of course not :-) but i don't really see the use for the numpad, unless you need to input a ton of numbers for work or something.
to me the numpad is just a useless part of a keyboard, really.. because a full-sized keyboard already has arrow keys, and above it the navigation keys. and of course the number row.
personally i quite like how it's done on the IBM F XT, to me it makes a lot of sense to have all navigation keys (including arrow keys) clustered together, and all right next to the enter key (rather than being seperated by some empty space).
not saying i think the F XT is an ideal layout, but i like that part about it. i also happen to like how the F-keys are a cluster on the left side, rather than a long row above the number keys.
edit: i guess what i'm saying is imo TK > TKL > full-sized
