> the vertical space that often gets pinched by toolbars and such, effectively squishing your working area to an even wider ratio. And when working with text (reading, writing), the left and right edges of my screen are just slabs of emptiness.

Absolutely agree, and it’s amazing/infuriating when people/companies don’t realise it. My mom’s old Asus could barely fit a few lines of text on its small screen after all its toolbars in chrome. You shouldn’t need to scroll multiple times to read a 3-paragraph email on a display where it fits if it were the only text! (And of course about 60% of the space on the sides was wasted.)

I don’t have a 3:2 display yet, though I do have an old 16:10 21” monitor which is alright. My ipad (10.9”) is okayish as well, but I’m planning to buy a 16” 3:2 portable monitor soon. Do you have an 3:2 screens?
