Hehe..... now I can RAZZ my brother! He works for Intel you see, management at that. Nothing to do with the design or manufacture, training I think it is but hes been bragging about the trip to China he just got back from a couple of weeks ago. Next time I go out to Arizona I'm gonna shove my usb3 external at him and mourn.
