I'm going to offer a use case for touch screens: Augmented reality (AR) development.
I think there's a real possibility that AR takes off in the next 1-5 years. The combination of LLMs + smaller AR glasses makes AR a viable computing platform.
For example, simple things like, "Where are my keys?" is a lot easier to solve if (a) you're wearing your AR glasses already and (b) they have access to a frontier LLM.
However, it's very difficult to simulate "touching something" in AR using a mouse/trackpad and keyboard. What if you want to "twist open" a peanut butter jar? I could imagine touching the screen and twisting my fingers in a rotational pattern along the top of the can.
