I'd love to demo Office 365's simultaneous edit functionality hidden somewhere behind that link to see how it compares to Google Docs, but after clicking through two links and seeing multiple pages that were trying to upsell me via "buy now" or "try for 90 days", I have to enter a whole bunch of identifying information to create a new account, and even choose a new, unique domain name. Want to see how Google docs works, which you don't even need to be signed in to google to view or edit? Then click this link: https://docs.google.com/spreadsheet/ccc?key=0AozKRH1Kuez_dGR...
