I wish this could be a poll, but there are so many choices. Mine is the most famous Think Different commercial featuring Einstein, Ghandi, Amelia Earhart, etc. I know it's such a well known commercial, but it's absoultely perfect! Apple should re-air this ad today. This ad can never get old. Although the "Think Different" ads weren't terribly successful, in my opinion they are the best. What is yours? Think Different!
