Perhaps not everyone at E3 got a chance to try a 3Ds. In fact, I'm reasonably sure that the MAJORITY of the people did not get the chance to hold a 3DS in their hands, less then 25%, much less even i'd imagine. And of course, of that portion of the people who did get the chance to try one, not everyone, in fact only a small minority of those people would run off and mention to a news media of any difficuties with the 3DS.
Just putting things in perspective.
