I sort of agree, but still ended up in the opposite corner. I use a keyboard which has no arrow keys and instead use <fn>-hjkl in every app with no (non-keyboard) configuration needed.

Also, combined with some other changes (the space bar is fn if depressed with another key, space bar otherwise; caps-lock is mapped to control; a couple somewhat more complicated macros), it is pretty effective at keeping others off my machine.

A programmable keyboard offers useful options.
