Nokia is not a software OS?

Symbian and the S-series have been running on more devices than Windows, if I am not mistaken. S40 alone has been on more than 1.5 billion devices.

Does that mean that Microsoft isn't a software company, too?

I am so fed up with the blatant trolls ruining this place, I think I will leave TMO for good soon. But then, that's why they're here.
