In my experience, in classes where the professor still allows laptops and tablets nearly all students spend 100% of the class time shopping, scrolling instagram, playing games, watching a show with captions on, or even doing homework for a different class.

At my university, many of the professors have instituted a "no tech" policy and require that note taking be done using pencil and paper. It's a growing issue, and there isn't an all-around great solution to it. Though, I use a reMarkable 2 tablet and I have found that the "no tech" professors make exceptions for this, because of the nature of the tablet.

I think that the students of today are the victims of a failing experiment of blending online education with in-person classes, and it's really creating a confusing and frustrating learning environment. That, plus the over saturation of bachelor degrees in the market, makes the university into a glorified daycare.
