I guess I'm just a luddite that spends my life on a CLI or text editor. Taking my hands away from my keyboard to leave finger prints on my screen just doesn't make sense to me.

I think people that do do tasks where a touch screen makes sense are probably just doing most of their work on an iphone or an ipad anyway.

Now gesture control on VR/AR setups? Sure, that feels like a new human/computer interaction system that makes sense. Jabbing at my laptop screen with one hand on my keyboard, not so much.
