Offline Gmail, Google Calendar and Google Docs:
As promised, Google brought back the offline mode for Gmail, Google Calendar and Google Docs. The updated apps use HTML5 features and no longer require the Gears plugin.
For Gmail, Google chose the easy way out and tweaked the tablet interface. You can only use it in Google Chrome after installing this app from the Chrome Web Store.
The app lets you archive and label email, compose new messages and read the messages you’ve received, but it doesn’t have all the features from the standard version. The interface is more suitable for tablets, so this is more like a temporary workaround instead of a definitive solution.
