Linux is only free if your time has no value.
Software Engineering might be science; but that's not what I do. I'm a hacker, not an engineer.
I think Linux is a great thing, in the big picture. It's a great hacker's tool, and it has a lot of potential to become something more.
And when the time comes to replace the O2 I have today, maybe my next machine will run Linux.
Of course, all of the software I write runs on Linux; that's the beauty of standards, and of cross-platform code. I don't have to run your OS, and you don't have to run mine, and we can use the same applications anyway!
Mostly I use the O2 as an X terminal, however, running my apps on Linux and displaying remotely.
On the other hand, there would be some value in different folks getting together to share expertise and technology; but to the listener, it wouldn't necessarily seem like a single station in the traditional sense.
I think Linux is a great thing, because Linux is an alternative to Windows, and because, of all the operating systems that are at all relevant today, Unix is the best of a bad lot.
