And Linux is not a success in the public arena. Sorry. Tech savy people think it's cool, and it is a great product, but it has zero market penetration for public use.

I strongly disagree with this. On the desktop, you might be right,

I'm not even sure I'd say he's right there, either. Taking a look at my companies host file shows:

lid3213:~> perl -ne "print if /\blid?\d+\./" /etc/hosts | wc -l
736
lid3213:~> perl -ne "print if /\blid\d+\./" /etc/hosts | wc -l
480
lid3213:~>

The first number is the number of linux machines we have. The second number is how many of those are desktop machines.
