Good comment on the ergonomic benefit, Elizabeth. Here's another ergonomic benefit. When my right hand leaves the keyboard to access my mouse, I have to return and make my index finger find the little bump on the J key (I'm a touch typist). Think of all the lost seconds in my career I have lost by doing this. This device means I never have to lose tactile sense of the keyboard.
Oh, gee, I wonder if it's possible to get a thumb cramp.
It's a good question, Rob. But I think there is still a use for a mouse in precision editing work, e.g., audio and video and photography. As you can tell from my handle (78RPM) I edit sound recordings of my huge 78RPM record collection going back to 1895. I also edit photos and drawings at the individual pixel level. For these applications, I need an accurate pointer. I just can't do this on a tablet because my fingertip is too big. Old fashioned I am, but I think the mouse and PC/Mac have some good years in their old age.
