Right, so you essentially use mini 16:27 screens which is a better aspect ratio than 16:9. What you really have to ask yourself is why 16:9 is a better choice than anything else. It wasn't picked because 3 16:27 columns is ideal for text. The main reason we have them is because it's easier for the screen manufacturers to have just one aspect ratio to deal with. With 16:9 we're forced to have three columns per screen, but what if I only need two? What if I want more lines of text per screen? Square seems like a much more obvious middle ground.
