No, not some secret nuclear research group in Los Alamos or Area 51. The Mojave Experiment was run by Microsoft last month and has not been blogged about much in the mainstream blogosphere (Engadget, Valleywag, Techcrunch). So I decided to give ol' MSFT a hand. They essentially did what Pepsi did with the "Pepsi Challenge" by blind-user testing people with Vista, claiming it was a new OS code-named Mojave. "Mojave" got much better reviews than Vista did - almost double the rating. This tells me nothing, because I was pretty happy with Vista when I started using it at work this summer. I would have got it earlier if my poor Dell Inspiron 600m could have taken it. Most of the anti-Vista sentiment is the visceral reaction of many people against everything from Redmond, combined with some harsh but creative "Get A Mac" ads out of 1 Infinite Loop.
