Good news from Google Today as they have released the Android application for their known office editor - Docs. And the same as the web application, the smartphone version is a full editor but has some extra features too.
So with Google Docs you can edit for free Word, Excel and PowerPoint files. With your Android device you can view Pdf documents and share any office files with contacts from your agenda. Then if you already have an office suite document in your phone, this can be uploaded and edited in the GMail account.
The application has a home screen widget integrated which can offer instant access to three core tasks: open any starred documents, create a new document and take a photo to upload. But most wonderful and useful feature of Google Docs for Android is the scanning. If you have a text paper document, this can be scanned and will turn from a photo into an editable Word, Excel or PowerPoint through the optical character recognition system. For now this is working only for English and is not to be used for hand-written documents. But you can convert any already taken photos from your device memory as this is working as a converter. They say that will be improved in time - perhaps support for other languages will be added.
I believe this is a great replacement for any other free office editor which can be found on Android Market but can also compete with many paid similar applications.
