Actually, I was talking about this kind of too-deliberate-to-be-true and trying-too-hard-to-look-cool atmosphere at Microsoft events, not about Bryan Roper's style in particular.
Well they chose him to represent them for a reason presumably, and it may be related to his ability to speak well. He's a little over the top but not to a fault in my opinion. It's close though.
Why would you extrapolate his persona to all of Microsoft?
