“It’s game time for Steven A. Ballmer, Microsoft’s chief executive. Microsoft disclosed a series of management changes on Tuesday that will alter the shape of its business unit responsible for products like the Zune music player, Xbox gaming console and phones. Most notably, Robbie Bach, the current head of the entertainment and devices group, will retire from Microsoft after 22 years at the company. As a result, Mr. Ballmer will take a more hands-on role in Microsoft’s gadgets and games by having various division heads report directly to him.” Maybe we’ll finally see an Xbox that doesn’t sound like a tornado. I recently finally got the opportunity to fiddle around with a PlayStation 3 (the big one), and by god, the Xbox is a joke, construction-wise, compared to Sony’s beast.
