I would love a trackball on a game controller in place of the right thumbstick. I just searched for such a controller and this study from the University I went to came up: http://www.yorku.ca/mack/FuturePlay2.html http://www.yorku.ca/mack/FuturePlay2.html Apparently gaming performance increased between 5 and 10 percent going from a traditional controller to a prototype trackball controller. In addition to that gaming performance increase, I wonder if a trackball could be put to better use in other more traditional UI situations that SteamOS has to implement (big-picture mode clover-leaf keyboard, scrolling, item selection...)
