This shows the difference between owning and reviewing.
Reviewers need something new to get their words heard above the noise. Since Model S already got great reviews, including a couple COY awards, no way another positive review will gather any attention. So, they look for things to complain about. Even if there's no external motive, the very act of reviewing is criticism, and they think their audience wants them to be critical but fair. Obviously, Tesla has had some unfair criticism.
Owners can report how well the car is working for them, and can gush about their purchase. That they overlook some flaws is natural and understandable, and I don't believe hurts their credibility. Unfortunately, this overly positive article (SF to LA in a 60kWH car with only 1 1hr stop?) can't come close to counter-balancing the overly critical articles. But, like SByer says, it's good to have.
