Normal computer means a choice of OS to run on it without having to hack it to do that job.
Chromebooks aren't sold as general-purpose computing devices. They aren't "normal computers" in the same sense that cell phones aren't.

I'm a CAD developer and user. I need Windows for my work.
I would hope that this forum includes people who are in touch with the real world.
