To be honest, I never rated Linus' technical knowledge very highly. He seems like someone who knows his way around the a few websites to order computer parts, but does he even have a computer science degree? Has he worked as a software developer? Does he work on Linux in his spare time or something?

That he was wrong about something highly technical does not surprise me. That he thought he could talk authoritatively about something he has never used or seen the specs of... doesn't surprise me either...
