Sources tell The Verge (pretty accurate with its Microsoft scoops) Satya Nadella will unveil an iPad Office suite at a March 27 San Francisco event where he'll talk up Microsoft's (MSFT) mobile and cloud ambitions. Currently, iPad users have to make do with the Office Web Apps.
Not surprisingly, the apps will require an Office 365 subscription, much like the Office iPhone and Android apps released last year. Since the release of those apps, Google has made its Quickoffice productivity suite free, and Apple has made its iWork suite free to buyers of new iDevices.
Office remains Microsoft's biggest money-maker: Before changing up its reporting, the company's Business Division (dominated by Office) had FY13 op. income of $16.2B, well above the $9.5B produced by the Windows unit and the $8.2B produced by Server & Tools.
In a move viewed by some as a prelude to an iPad launch, Microsoft recently rolled out a Personal edition of Office 365 that goes for only $70/year, 30% less than Office Home Premium (supports up to 5 PCs).
