I already made the switch to Linux a couple of weeks ago. I also have helped some others with there Linux OS's. I've been endorsing it and the more people I can reach and word spreads the better. If no one is buying then maybe they will change. But I doubt it. I now have mono develop but am gravitating towards other languages instead, like C/C++, Java, Python, or Perl. The KDE development environment is very nice! I've already got about 4 or 5 people that switched there OS's.
