Check out this video of Microsoft CEO Steve Ballmer autographing a MacBook Pro at Trevecca Nazarene University in Nashville, Tenessee. Say what you will about Ballmer (he’s crazy, a bad CEO), but he seems to have a good sense of humor about things. Ballmer comically signed the MacBook Pro with a note stating, “Need a new one?” The student, for what its worth, promised Ballmer that the MacBook had a copy of Windows on it.
