I have been advocating the idea of a switch to easily turn off rumble in the past, a PS3 system setting dealing with the issue would be nice as well. I don't like to go through the menus for every game I play to turn this off, with the current Sixaxis I simply don't have to deal with it. 
I like the lightweight controller the Sixaxis is, some are of the opinion this makes the Sixaxis feel cheap, but I don't share this opinion. My cordless keyboard is also pretty lightweight.
Rumble would be a waste of battery life and most often a distraction for me (other uses than gun vibration). I would rather have real force feedback optional, meaning to me that the sticks would somehow have the ability to provide some resistance, for example while walking against a snow storm.
