I keep telling it will be the second coming of how Netbooks went down, but people are too busy praising Valve for translating Windows APIs, instead of actually building a gaming ecosystem on Linux technologies.

The same kind of technologies that power Android NDK, and to lesser extent PlayStation Orbis OS, with its FreeBSD roots.

AAA Game studios don't see a reason for directly supporting Linux and if Valve is willing to do that for free, even better.
