CNET News.com reports:

Spurred by an e-mail from someone deep in the marketing ranks, Microsoft last week traveled to San Francisco, rounding up Windows XP users who had negative impressions of Vista. The subjects were put on video, asked about their Vista impressions, and then shown a “new” operating system, code-named Mojave. More than 90 percent gave positive feedback on what they saw. Then they were told that “Mojave” was actually Windows Vista.

Sounds a little like the “Folger’s Switch” from years ago.

Instead trying this on XP fans, try it with some Mac-vangelists or fellow Linux fans.  Then you’ll impress me.
