I'd love to have a 4:3 laptop again. Best general use display. I find it amazing how we have been forced to use widescreens for so long yet our content, except for movies, still doesn't fit it. Office documents can fit on screen. Websites have to pad endless whitespace on the sides. The list goes on. We need to return to 4:3.

It is my belief that wider aspect ratio displays are easier to manufacture, too.

At a given pixel-pitch, you need fewer rows. In extremis, imagine a display that is N x 1 -- much easier to limit defects and handle the necessary multiplexing.
