I used to use a Chromebook running Ubuntu that had a built-in touchscreen, and it was nice. A lot of websites build with touch in mind now, so having access to that kind of interaction ends up being a pleasant add-on.

Instead of thinking of it as a screen upgrade, think of it as a trackpad upgrade. The touchscreen on this Chromebook wasn't even that good, and I still really appreciate it having it. I'm sure one on a MacBook pro would be a really nice experience.
