So part of the new Vista marketing effort called The "Mojave Experiment" is online.
Not a lot to say about this, I give this about the same amount of credibility as I do to late night infomercials, paid programs on afternoon TV, and any commercial with a "(*) based on laboratory results" in tiny lettering at the bottom of the screen.
I could say that these were edited to make the people's assessments of Vista worse than it sounds and their assessments of "Mojave" better, but this is as "real" as a reality TV show, and shouldn't be seen as anything more than what it is, a commercial, and it's content should be taken with that in mind.
Please note I have Vista Ultimate at home and am perfectly satisfied with it.
