To make a screen with any ratios other than 16:9 seems to be very expensive nowadays though. I personally would rather a laptop be cheaper than to have a 16:10 or 3:2 monitor.

Then again, it would probably be only visible in greater margin for the manufacturer :/.

It's probably not that they're much more expensive to make, but there are much better economies of scale with a 16:9 ratio... the same panels work for TVs too

There isn't a market for 13-inch TVs... But mathematics support your reasoning about economies of scale: with constant, 13.3 inch diagonal, higher the aspect ratio, lower the screen area,thus less raw materials used, cheaper to produce.
