I used to when I ran dual 24" monitors! We had really sweet old IBM monitor stands that could tilt, raise and rotate. You had to be quick to grab them from the copy room before the electronics pickup. I swiped one from the still warm desk of a colleague on the way to their farewell happy hour.

So I had a '14 13"(? Might have been 15" but probably not) RMBP on the left with email and chat stuff, 24" main monitor in landscape and then another 24" monitor in portrait on the right. I think at some point I put a newer panel on the IBM mount. It was sweet.

Back then we still had desktop PCs at our actual desks so there was a KVM on the main monitor! What a time to be alive!

These days I do prefer a single monitor workflow if possible. It's just cleaner and move convenient.

I think my dream set up would be a 27" 1440P (What I currently have at home, with a pair of smaller (19" maybe?) 1080p screens on either side setup in portrait. Basically a similar screen area to 2x27", but without a bezel right in the center of my field of view, and the 1080x1920 screens will be a good size for displaying full page (e.g. PDF) at more or less full screen.
