Speaking of which, of all the features of the Wii, I actually think the two-handed controller idea is ace too. Resting both hands more naturally (when I was playing Zelda mainly).
That is one of the things I really like about the Wii controls, it's the first setup in years that i've been able to play for relatively long periods without discomfort.
It's much more comfortable for me (fairly large hands) to use, it allows people to determine themselves how far apart they hold the controls - i'm not sitting with my hands cramped around a controller that is too small, nor am I struggling to reach oddly positioned buttons because it's been designed for the Jolly Green Giant.
