I hear this complaint a lot and I think it's based on a flawed premise.
Taller aspects might be better on very small screens that only fill tiny portions of your vision but on bigger screens -- the sort you should be using if you're working regularly on a computer -- you want wider not taller. It's the only way to usefully use your field of view. This is why wider aspects exist.
On my 16:9 aspect 27" desktop screen, my vision is practically filled in the vertical direction -- it is easier to glance to the horizontal edges than the vertical ones. I would use more horizontal space before I used more vertical.
And this is the point of wider aspects -- they use your eyes better. If you buy three screens for your desktop, you don't stack them vertically -- you arrange them horizontally so you can actually see them.
People who keep asking for squarer displays for work should simply get bigger displays and stop pretending that a 13" laptop display is ever a good choice for a working display.
Frankly, anything sub 24" is not a working environment. Anything smaller is either (a) something you use occasionally when you're not at your desk or (b) for people who are not working.
