It is good to be able to see what you'll get before you pay. However, this does allow you to explore the app's features and design as a sort of demo. You won't be able to make or edit documents with the free version. I am told that app versions of these programs are coming to the Windows 8 app store soon for you Windows tablet users.
In many ways, these apps have a more efficient and more intuitive design than the actual Office programs on Windows 8 PC's (at least with regards to touch controls). Excellent Design: I did not try making any new documents, but I was very impressed with all the menus and the interface.Just swipe one direction to do the next animation and swipe the other direction to back up. The official PowerPoint app, however, can play all animations normally. PPT files but would be unable to play the animations. PowerPoint Transitions: I've always been bummed out by iPad apps that would load.These apps load the original documents correctly without having to save them as PDF's. Maintains Your Formatting: I've always had to save my Word and PowerPoint documents as PDF's before loading them with iPad apps to maintain their visual look and proper formatting.Syncs Seamlessly With OneDrive: When you load the various apps, your recent documents and your OneDrive folders will be right there for you to browse through.
