The Studio Monitor Lie- Do you need them?

In this video I give my opinion on whether or not you even need studio monitors. I use monitors currently, but for years i used headphones and home stereo speakers. Last year i made a promotional demo for wife that was mixed on headphones and my macbook pro's built in speakers- and she's landed many gigs from the demo! As long as you understand your playback system and use reference material, it doesn't matter! Your mixing skills are far more important than what speakers you mix on.
Since this is an opinion video, tell me what YOU think? What's your opinion on the matter? Let's hear it in the comments!
