I’ve recently become a big fan of Google Apps and it really kicks in if you have an Android phone. Here’s yet another great feature!
Mobile editing: Log in to your Google Docs on a browser on a supported device, and select the document you want to edit. Then, when you’re viewing it, press the ‘Edit’ button to switch to the mobile editor. If you use an Android device with voice input, you can also use this to add text to your document.
