Those windows controls on the left was the result of UI experiments. The mouse travels less when the controls are on the left. Imagine launching an application with the launcher on the left, and when you want to close to close the application, you have to move the mouse aaalllll the way to the right. It is not a breathtaking innovation as OS/X had been doing it already.

You can learn to use the windows controls on the left. I got used to using them and it takes a few days to feel at home. When sadly Ubuntu switched back to GNOME Shell and reverted this change, it felt really unnatural to have those windows controls on the wrong side. Still, you get used to it after a few days.
