Google Docs Support .xlsx and .docx Now
Until now, i start use Google Docs more and more. It's easy to collect information by Google Docs Form. You can build a Simple Form, Edit, Share and Send it to anybody of your Gamil contacts.
I will upload few documents to Google Docs like PDF, doc etcs sometimes. Beacuse i can accept these files when i logon Google Docs by computer or mobile device. Now, it'a good news for Microsoft Office 2007 users. Google Docs support user can upload .xlsx and .docx now. But not including .pptx.
