In the year that I had a Surface, I can count on 2 hands the number of times that I used the touch screen. Out of all those times that I used touch screen functionality, the majority of the times were done inadvertently when I was trying to get something off the screen. I'm willing to bet a lot of people won't/don't care about the touch screen, they just want something cheap.

I have a Windows laptop with a touch screen. The only time I touch the screen is when I take a screenshot using the Snipping Tool and want to circle something.
