Steve Ballmer sells operating systems, spreadsheet and word processing software. His performative manners however are reminiscent of a fanatical priest, hyped-up market-trader or dogged show-fighter. Where does he get his energy? Which forces drive him towards this high octane show? A curious mixture of technical euphoria, testosterone and capitalist optimism culminates in Ballmer’s eccentric stage appearance in front of Microsoft employees. Half-amused and half-horrified, with a mixture of embarrassment and unease, you can neither watch nor turn away.
