I've heard different, conflicting accounts about Ballmer's stance on Xbox. Originally, I read that he was dead set against making a console and wanted to sell "Windows OS for Game Consoles" to companies like Dell. Other accounts say he was a supporter of Microsoft getting into the hardware business. Not sure which is correct, or if he switched over to the winning team. I recall reading one of those accounts from an interview with either J Allard or Robbie Bach.
