I recently acquired one thinking it was going to be a cool and useful feature, and the only time I think to use it is when I brush away a loose cat hair and my cursor goes all over the place. And the tablet mode, I think I used it once as a novelty.
Work laptop. I use it when I’m sharing my screen and we’re discussing a map or drawing of something. Pretty useful. Especially the pinch zoom function when whatever app I’m using doesn’t have an intuitive zoom function.
Not work laptop. If I’m reading an article on the couch sometimes I’ll scroll down using the touch screen.
