The world is full of devices associated with the word ergonomic. A scholar trying to learn the word by studying the way it’s used in today’s culture is likely conclude that it means “curvy” or possibly “funny-looking.” Nearly all mice, trackballs, and other devices are now described as ergonomic; this doesn’t mean they’re all good for you to use.
Unfortunately, unless you use a given gizmo for a few hours, it’s hard to get a feel for how it will work for you. Still, experimentation is the tried-and-true method to determine the level of ergonomic satisfaction you will get from a device. —Peter Seebach —Tools to keep the user from being hurt (IBM)

The three machines -- work, home, and laptop -- have three different pointers -- mouse, touchpad, and trackball, respectively. I suppose that spreads out the injuries across more muscles. My new laptop doesn't have a little stubby pointer integrated into the keyboard, but I almost never used it anyway.
Often towards the end of term I find myself dictating responses to student papers. It doesn't really save me any time, since I have to edit what I dictate, but it keeps me amused as I deal with stacks of rough drafts.
Exactly right. I use touchpads now almost exclusively--I tolerate them much better than a mouse.
