I feel that you're mostly right. However I think we all focus on different details, to an extent.

For example, I'm a great typist so the underscore key has never really bothered me.

But to call the author out on being detail oriented would be inane of me. I myself don't like keyboards that have small backspace keys. I also still hate OS X for having the window control cluster on the top-left corner.

I know I certainly get paid to think about the details. The only variable here is which details.
