If you don't mind a link to Kotaku, there are some interesting impressions on there, particularly this bit: > "This sounds weird, but it's almost like rolling two weighted trackballs that are too large to actually fit into the controller," Lambe said as he tried to explain what it's like to have one's thumbs on those two trackpads. "For camera controls, slide one thumb to the right, and you'll feel this ticking, like you're turning a physical control. Flick your thumb quickly, and this imaginary physical thing reacts like something with weight to it—the 'trackball' continues to roll for a bit, eventually coming to a rest. And since it's all controlled through the software, the same trackpad then becomes more like a mouse or a laptop trackpad when you're navigating through menus." http://kotaku.com/valves-controller-has-been-tested-here-are-some-impre-1415579308 http://kotaku.com/valves-controller-has-been-tested-here-are...
