A recent upgrade to the Mac operating system moves Apple closer to challenging Microsoft for overall computing dominance, even in the corporate market.
The 20-year death grip that Microsoft has held on the core of computing is finally weakening-pried loose with just two fingers. With one finger you press "Control" and with the other you press "right arrow." Instantly you switch from a Macintosh operating system (OS) to a Microsoft Windows OS. Then, with another two-finger press, you switch back again. So as you edit family pictures, you might use Mac's iPhoto. And when you want to access your corporate e-mail, you can switch back instantly to Microsoft Exchange.
