Microsoft's Office suite has been downloaded to 12 million Apple iPad users
While downloading the Office suite app is free, you are limited to viewing previously made documents, and presenting them. To start a new document, or to perform any editing functions, iPad owners will need to subscribe to Office 365. A one-year subscription is $99.99 which can be paid as an in-app purchase. Students pay $79.99 for the university edition, and later this year Microsoft will make available a $69.99 personal subscription. Microsoft has not revealed the number of such subscriptions it has received from iPad users. Earlier this year, some analysts concluded that Microsoft was losing out on $2.5 billion a year in revenue by not offering the Office suite to users of Apple's iOS flavored slates.
