An unscientific survey conducted by the survey and recommendation website Hunch.com has reinforced some data already broadly known about Mac people versus Windows people -- and also shown up some surprising differences and similarities. The website used answers from over 300,000 respondents on this latest survey, and also compared the answers to a similar match-up it did in November 2009. One clear result: Apple's casting of younger, more casual Justin Long as a Mac and John Hodgman as the stuffier, older PC in the long-running "Mac and PC" ads was no accident.
