“Today’s web apps only work when they’re connected to the internet. We realize there are times when you can’t access your email because of an unreliable or unavailable connection.

…Offline gmail allows you to open a browser, access your inbox, and use all of gmail’s familiar features even when you don’t have internet access. Gmail caches the action you take on your computer while constantly searching for a connection in the background. When it finds one, gmail sends the messages stored in your outbox, checks for new mail, and automatically syncs the changes you made while offline with google servers.”
