Google is launching a new Gmail web app and updates to Calendar and Docs, in an effort to increase its products’ offline utility. Google Customers have been asking for ages for offline access to email and calendar, now Google will introduce a HTML5 Google Chrome App. It looks similar to the tablet version of the site if you visit it on an iPad, Xoom, Touchpad etc.
You can’t edit documents in offline mode but Google is trying to integrate it. The Apps are currently in the Chrome Web Store.
