i think he was saying thay he's shot more sd cards - in a professional enviroment - than we've had hot dinners, and that we shouldn't get hung up about it, they are reliable but just use a bit of common sense, buy good cards, fomat well, change often if you can't backup, don't mix on other cameras, etc., all very good advice.
however, everyone has a right to their own particular hangups, and the right to ignore someone with more practical experience than ourselves... take my 9 year old for example... (joke.)
