Windows is regaining some of its marketshare, claims Microsoft CEO Steve Ballmer. "Weíre gaining share. Apple is expensive," Ballmer says in a new interview. "And in tough economic environment, people get it. Their [Apple's] model is, by definition, expensive. And weíve actually held or maybe even gained just a tiny bit of share relative to the Mac in the last 12 months. And itís not really Snow Leopard. Itís really Windows PCs versus Mac."
