I'd be interested in more modern studies on this. 1989 I didn't really use the mouse that much it really was amigas / ataris / macs and those interfaces were really built for mice. Also you need to make a distinction between applications you use all day every day and applications you use sometimes. A lot of games achieve a lot through mouse/keyboard cooperation. As do people in various designers photoshop/blender/unity etc For coding, a lot is achieved through things like VIM bindings. Then we have things like browsers, which are really mouse first UIs that you can drive through keyboard and enhance with plugins like Vimium. Also add into the mix trackpads. Useless for somethings, awesome for other things ( especially through multitouch gesturing ) So, all these scenarios it would be interesting to have a thorough analysis of perceived speed, actual speed, etc.
