News Summary: Microsoft brings Office to iPhone
NEW SOFTWARE: Microsoft is making a pared-down version of its Office software package available on the iPhone.
MISSING: The company is holding out on extending that to the iPad and Android devices. It's trying to boost tablet computers running its own Windows system, which can run the regular version of Office.
ANOTHER CATCH: Microsoft also isn't selling Office Mobile for iPhone separately. Instead, it comes as part of a $100-a-year Office 365 subscription, which also lets you use Office on up to five Mac and Windows computers. Microsoft said it wants to give customers yet another reason to embrace subscriptions.
