Microsoft stock has jumped a bit, close to $40 a share, due to the leak of the announcement of Office for iOS devices. Many iPad users have been needing a version of Office to do work on the iPad while on the go. This should satisfy a lot of education users as well as home users looking for a good Office suite on the tablet.

The Redmond, Washington-based company will introduce Office for the iPad with limited capabilities that can be upgraded to premium versions requiring a subscription to the Office 365 Internet-based software, said the people, who asked not to be identified because the plans aren’t public. At the event, which will be held March 27 in San Francisco, Nadella will also discuss his commitment to software services that work on Microsoft’s Windows and rival operating systems, the people said yesterday.
