Decide First; Don't Let Facts Get in the Way
There are a ton of people out there convinced that Vista is a horrible flop, like, say, Tim Beyers, here at the Fool. Having used Vista for months now, I could never understand why folks who don't use it would continue to bash it the way they due, and I was pretty sure this was just an example of common knowledge being pretty unknowledgeable. Between those smarmy Mac/PC ads telling blatant fibs about the intrusiveness of Vista's security features like UAC, and the feedback loop you get from a know-little, knee-jerk media in the states, I figured people were making up their minds having never even seen it.
Turns out, there's a little experiment that supports that notion. Pretty funny stuff.
