Google Docs also makes Office 2003 and 2007

Of course, you probably already own Office 2003 or 2007 (or maybe Office 2000?), and there's no need to uninstall them. Fortunately, Google Docs also makes Office 2003 and 2007 better. For example, you can store any file – including Microsoft Office documents – in Google's cloud and share them in their original format (protected, naturally by Google's synchronous replication across datacenters). Plus, in the coming months, Google will enable real-time collaboration directly in Office 2003 and 2007, as you can see here.
