The eDGe comes with Documents To Go from DataViz, which includes simple versions of the key Microsoft Office apps (Word, Excel & PowerPoint). This app is intended for word processing on the eDGe. If you go to the DataViz website, you can find the Help file for the Android version to get an idea of its capabilities.

I've seen at least one other "office" suites for Android devices, but you have to buy them, and from my brief look at the product website, they aren't significantly better than Documents to Go.
