Most of my professors are guilty of this. The only exceptions I've seen so far are math professors who use the chalk, and a programming professor who writes on her thinkpad x-series tablet hooked up to the projector. That's pretty neat, actually.
I have found what you say to be especially true in first-year courses... several of my professors are only here to finish their doctorate and they're just teaching this puny 200-level course because they have to / because it's some spare cash and they don't really know or care as much as they should.
I agree... when something on my Windows machine breaks, I have to either spend ages searching the Interwebs for solutions that probably aren't there, reinstall/reboot and hope it works better next time, or (gods below) call tech support.
When something on my Linux machine breaks, there's usually several relevant communities around where I can search for / post my problem and get help fixing it. Linux has been a much nicer experience for me as far as troubleshooting problems goes.
