Some of you folks sure are darn pessimistic about the Steam controller. It's not a Kinect or a Wii remote; it actually could evolve standard game controls in a far more meaningful way that those two couldn't.
I like the idea of controlling the mouse with it, it'll allow me to play old point'n'click adventures.
I greatly disagree, I find the build quality to be excellent. The PS3 controller felt like a flimsy turd, and the Wii wasn't much better!
