Developing applications for touch devices is much nicer on a laptop with a touchscreen.

I thought I would never use one either, but whenever I use my SO's laptop with touchscreen, I keep touching the screen for "quick actions" like pausing video or starting apps or moving things around. I don't use it when I need precision, but when I need to just do one thing quickly where I don't need accuracy, I actually find it really handy.

But I wouldn't pay (much) extra for it.

Touchscreen is one of those things that sound nice, but in my experience are not so useful. At least not for my typical use (programming, writing, even CAD design). Before having a framework 13 I had a dell xps 13 with touchscreen for about ten years. I never really had a use for it. But hey, the rest of the specs of the screen alone make it still a nice upgrade possibility for the future :)
