An anonymous reader writes: Google has added native Microsoft Office file editing to the dev channel for Chrome OS. The addition means Chrome OS users on the latest build of the company’s browser-based operating system can now experiment with editing Microsoft Word and Excel files. The dev channel for Chrome OS is updated once or twice weekly. Since the feature has made it in there, it's likely to show up in the beta channel, and then eventually the stable channel. Today's news that Google is already working on editing, and not just viewing, Microsoft Office documents in Chrome OS is very interesting because of the potential. Maybe by the end of year, the functionality will make it into the Chrome browser too.
