According to distrowatch.com the number one downloaded distro is Ubuntu.
In terms of Linux that is sold, RedHat is indeed number one, followed by SuSE.
Really? That is surprising. I have used Ubuntu and like it. I would have assumed SuSe was downloaded more. Thanks for the info.
Just out of curiosity, do you know which PC's have Linux pre-installed? I have a brother who wants to work with Linux and is in the market for a new PC. He's a total MS guy but wants to check out other options.
