Interestingly I find that while you can doom scroll on a laptop for me it doesn’t “work”. Perhaps because my laptop is work territory (both actual work and hobby) so I automatically don’t doom scroll there or maybe it’s just that lots of content is optimised for mobile and the experience is “better”.

I pretty much never use a phone, and all my screen time is a computer.

How do you even mindlessly watch youtube vid after youtube vid on such a tiny screen?

Also, I always carry my phone, I don't carry my laptop most of the time. Pulling out your non-work laptop in a boring meeting is also something you don't do.
