So your argument is that there are a huge number of people not complaining about the Rio, but your individual experience overrides all of that?

As I stated quite clearly, my experience and the experiences of others on this board and elsewhere.

... firtst you say that the forums are brimming with people not complaining, but then that the experiences of the few that do have problems are more than that. Which is it?

My observation that the board is loaded with people who aren't complaining was in response to tfabris' claim that "on bulletin boards, you only ever see the people who are having trouble," which is patently preposterous.

I also see numerous posts that do not speak well about the quality of the Karma (bad firmware, frequent lock-ups, parts coming off, etc.).

What is difficult to understand or accept about this? It's not some kind of zero-sum game, in which favor or disfavor of the Karma eclipses its opposite.
