1) He's presenting about using Linux
2) He's presenting at a Linux conference
3) He's presenting using Windows

I wouldn't be surprised if other people presented with Windows, but they hid it well. His only mistake was to leave the projector plugged in after the presentation.

Yes there are people out there that passionately hate Windows, but let's not forget that there are intelligent people that know that Windows is better than Linux in some aspects. Over the few days at the conference I met a _lot_ of very intelligent people and many of them agree with me. I guess what I am trying to say is: use the right tool for the right job.
