No malice intended, and if Gates did actually say that I apologize, but I just happened to remember Job's "Picasa" quote and looked it up.
The Jobs video was posted in 2007. It does not give a date (that I saw) of when he made that statement.
The statment I was referring to was made over 10 years ago at a techno conference/interview about technology and its development. I am pretty sure it was made by Gates.
