This is the most ridiculous headline of the past three years! And it didn't have to pass muster with Apple's PR people either.
Comparing the ONLY OS available to a platform (OS X) to the most failed, unpopular OSs (Windows Vista) is like comparing Chad Ococinco's failed marriage (and the attendant publicity to Basketball Wives) to Henry Fonda's screen marriage in On Golden Pond!
