I have one, never had the muscle memory for it. And never really used it. until I was using the machine in a moving vehicle on a rough road. and under those circumstances it was amazing how much better the point was than the pad. I was converted.

This is why I dislike touchscrens in cars, for the most part touchscreen are fine(ish) you loose most feedback, but you gain a lot of flexibility in display. fine for most day to day use. Until you try to use one on a rough road, then it is just hell.

Somewhat related, a few years ago when the first spacex manned capsule was launched, I gave an audible gasp when I saw they used touch screens, what idiot certified that, rocket launch is a very vibrating environment. I bet the touch screens were unusable during liftoff. However those spacex touchscreens did have one redeeming feature I would like to see on car touch screens. A bar to steady your hand while using it.
