Professional Starcraft players are able to perform 300+ actions per minute with a mouse and keyboard. For the average user, I think this would be plenty.
Point of order: the Professional Starcraft Player(TM) is not the average user, the skills of the Professional Starcraft Player(TM) are not representative of those possessed by the average user, and the command input structure of Starcraft is not representative of all computer programs.
We are not discussing professionals in specialised programs here - this is average users, in generic apps, and attempting to make the GUI more intuitive and powerful.

Ooh, low cut top! Zoom zoom zoom!
Wait, the wind is picking up! Initiate scan for pleated skirts!
Or female?
Ooh, there's a sale over there! *zoom* Do they have my colour?
Wait, that handbag's a knockoff! *Dials DHS*
What will they do with people outside the US where the DMCA does not apply?
Get the US government to invade them?
Or offer them a Free Trade Agreement. Bloody John Howard. Caterpillar-browed bastard.
