I don’t understand touchscreens on laptops that aren’t designed to fold flat. It’s got the feel of finger painting an unconstrained birthday balloon.
You're essentially holding a large tablet upright, but all the weight is taken up up the base. Rather than finger-painting, try holding it on both sides like a tablet or gamepad and operating with thumbs.
Scrolling/controlling checkboxes and switches feels GREAT. Depends entirely what you're using it for.
I had a laptop that folded to 180, without touch screen, and had a webcam hidden under F7 so it either looked straight up your nose or showed your huge fingers
