Not just a laptop
I’ve been using multiple monitors since basically forever, it gave me space to put windows on and I didn’t need to think about organizing them. A bad decision in retrospect: there were lots of distracting windows.

And you can just ignore all the coffee stuff …
Not just a laptop
I just mentioned that multiple monitors were a risk for distraction. And I therefore removed them.

This really helped me to work focused for a lot longer without short disruptions. And there’s also a way smaller obstacle to work from somewhere else than my desk.
Conclusion
Removing monitors might really help some people.
You may just try it. There’s not a lot of effort in doing so, except when your cable management is not so neat 😉
