You made me realize again how much I miss the 1920x1200 screen of my HP 8740w.
I'm on a ZBook now, and even though full HD, or a multiplier thereof, is more standardized, I still miss 16:10 enormously.
Also, Apple has stuck to 16:10 with MacBook Pro’s this entire time, with exception of the latest 14” and 16” models, which are 16:10 but with extra vertical pixels for the menubar to “live” in.
