My company once gave me a touchscreen laptop and I did know that until I touched the screen by accident. It was fun to play but I never found it useful. I heard many people saying the same, some of them even preferred to disable. I find it uncomfortable to touch a laptop screen... The only thing seems to benefit from that for me is photo editing apps or 3D modelling.

So, I'm curious about how you use it. Do you have a specific use case where touchscreen made you life easier?
