They will defend Microsoft at every turn and they will attack Google in every comment they make about them. Their posting history is very desciptive.
It is funny to read how quickly a news.ycombinator discussion degenerates when talking about Google, Microsoft or Apple.
What's funny is that in my experience, these denigrating terms came from each system's users, not from "the opposing tribe."
At my school we used the TRS-80, and constantly bemoaned its (many) faults, and dreamed of having Apple IIs ... and then one time we went to a computer show and met some kids from another school which used Apple IIs—who told us how much they hated their Crapples and how they wished they had TRS-80s... ><
Offhand I can list mtgx, rbanffy(who mentions he hates Microsoft in his HN profile page), or Toshio and lots of iOS fans and Google fans and employees and nobody seems to get bothered by them but somehow it's not okay for Microsoft fans to post on here?
