Well, I wasn't meaning 22 inch vertically.
Although I guess you could get one of those screens that turn 90 degrees, problem solved, right?
Seriously though, it's the diagonal, which does give some handy extra space.
And for the choice question, too much can be a problem too. I've taught and been taught, and there's enough of it with icons, menus, and shortcuts. Are we going to add the ribbon as well?
I guess so for some, but a lot of folks, good productive people, get lost in what went before and need a good, big, fat, visual cue. Not me though.
