Full-size arrow keys: by adding another column of keys to the right side of the keyboard. That way you get dedicated Home/End/PageUp/PageDown keys as well. See [1].
Grouping function keys: also put a wider gap between Esc and F1, F12 and Delete.
Mac keyboard: that'd be nice! How compatible are they to hackintosh BTW?
