Are you seriously making auto company comparisons, because there has never been a recall (tweak) by any car company right, only when they put out a bad product people often die or their lives are otherwise endangered, and they launch on a massive scale not to 600 customers, often with knowledge of product imperfections.
Please choose a better example, in any case at this point sfio has sold to 600 or so not tens of thousands, so gripiing about being used as a test group is ludicrous, would you rather they had waited another six months and lost every advantage in the marketplace?
