Sometimes, if I’ve been using my iPad for awhile and switch over to my MBP, I might reach out and touch the screen out of habit. I can’t be the only one.

I had the opposite problem when work issued me a ThinkPad - I would accidentally brush my screen with my caveman knuckles once a day and somehow nuke a dozen lines of code.

My kids do this all the time. They also use the touchscreen in conventional laptop configuration (not folded-flat tablet mode) on their Chromebooks all the time. It's bizarre to me. I'm always trying to get them to use the keyboard, but they don't care. Example: enter password on the keyboard, then tap the log in button on the screen with their finger, rather than just pressing enter. ¯\_(ツ)_/¯
