Or just buy everyone desktops. Honestly I think laptops are completely superfluous for every business I've ever worked at. Nobody is truly getting value out of bringing a laptop to meetings, they just like them.

I think whatever companies you were at just didn't have very effective meetings. There's a time for "laptops down" and there's a time for laptops. If we can't prototype, brainstorm, outline ideas... why even have meetings in the first place?
