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?

Or is it that there are too few people not complaining but ``brimming'' in some other way?

It's probably a bad idea to change your thesis in the middle of your post. At least without editing.

I mean, I don't own a Karma and I'm not going to defend it or excoriate it (since I have no data to do so), but 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?

Of course, the RMA problem seems to be well documented for those unfortunate few (or many?) who are having problems. There's no defense for that.
