I doubt that Microsoft has copied anything from the Linux ecosystem. And with Linux innovations such as moving the window buttons around for no reason and upsetting their users, I don't see why they would.

Linux fans need to relax a bit and realize they're number three for a reason and work harder not complain harder.

Edid: I'm sorry, do I sound bitter? Maybe I've grown disillusioned with the difference between the reality in the trenches and fans extolling the features of product X, where X is any of Linux, Mac, Windows, iPhone, etc.
