No and I never will. Facebook cannot do anything to change that because I simply don't trust Facebook enough to use their messaging system as my primary email system. Having said that, I also feel that Facebook messaging is greatly inferior to real email, especially modern clients like gmail. Besides the lack of bcc and a terrible interface (certainly in comparison to eg, gmail), in the past year, Facebook has failed to deliver/lost messages from people I know on multiple occasions.
