Microsoft recently launched the Office for iPad Product Guide, which is a PDF document containing information about all available features for those who install the app on their tablets.
“Now your Microsoft Office documents look better than ever on iPad! The Word, Excel and PowerPoint apps have the familiar Office look and feel along with an intuitive touch experience, so you’ll be up and running in no time. With the free apps, you can read Word documents, use Excel data and present with PowerPoint. With an Office 365 subscription, you can edit and create new documents with the iPad. Download the Office for iPad Product Guide to learn more,” Microsoft says in the description of the product guide.
Office for iPad is completely free if you only want to view documents on the tablet, but for editing features you'll have to purchase an Office 365 subscription.
