What class do you play that you only need 9 keybinds and you don't click things?
I know with my toons I have 30 to 50 each with 1 to 5 of those being cd macros or things of that nature. For most classes just interrupts, offensive and defensive cds and any sort of purge/debuffing type of spells will eat up 10 things.

The logitech version of the naga is far more reliable and slightly cheaper. It is hard to not pick the choice that cost less and lasts longer.
