How can I create and edit Microsoft Office documents in Android I'm looking for a way to create and/or edit Microsoft Office compatible documents (.doc/.docx, .xls/.xlsx, .ppt/.pptx...) on my Android device.  Are there any free solution that will allow me to do this?
If you are willing to substitute Google Docs for Microsoft Officer there are a number of free options.  

If Microsoft Office compatibility is a must there is a free app called OliveOfficePremium.  It allows for editing of Word, Excel and Powerpoint documents.  It is free but it has somewhat mixed reviews. 

Most of the other Office compatible apps offer a free version that usually only allows you to view docs, and a premium version (usually $10 or more) to edit.
