I guess smugness is in the eye of the beholder.
It's not smug when Thurott says "Hello, Windows 8? This is iPad. You win."?
It's not smug when Ballmer dismisses every Apple product when it's released only to watch that product become a smash hit?
Don't get me wrong Gruber's smug as all hell in this piece but Apple itself? I'm not so sure that shoe fits although a couple examples come to mind (like Steve's projection of Safari browser share).
