From the voting so far, it seems that forumites are evenly split between mouse-pushers and key-punchers.
In case you were wondering, I never had any thoughts of dropping either of these options - I was just curious to know how many people use each. I always guessed that keyboard players would be in the minority. Possibly they are a minority of players as a whole, but the forum regulars may not be completely typical - being more in the category of "power users".
