I prefer to use my multi-touch keyboard instead.
The keys stay tactile, and you can use the whole keyboard surface like a large touchpad.
Apple bought them. Hence seeing the technology in iPhone multitouch, gestures, recently in touchpads and now mouse.
I never timed, but it never felt like I was typing very slowly once I got used to it. The gestures like opening/closing a window, exiting an app, copy and paste etc is really handy. Especially as they apply across all apps, not just within a specific editor. The gestures are also configurable, and supports different OS modes. Most importantly, it reduced the pain in my wrists and fingers (might just have been a side effect of typing slower).
Bought it about 6 years ago, have been using it since. Was pretty disappointed when I heard the company has closed down. And a few years later when I heard about the iPhone pinch gestures, my first thought was - this must be the reason!
