Acer Aspire 4738ZG keyboards problem

The Acer Aspire 4738ZG Keyboard Replacement Brand New US Layout is set out to work for how words are spelt and what letters are used the most.
Have you noticed how ERS are close to each other? They're used a lot together.
How about hoe QWZ are kinda out of the way that the edge? Who users those keys? Not me, I can tell you that for free?

Is what I said the actual reason? No, it's just a guess. I've never actually done any research on the matter. It's just what makes most sense.

For all I know, the letters could have just been thrown on the floor and picked up and placed randomly.

But on a serious note - it was probably designed this way to work better for the touch typer
