According to the Google Chrome Blog:
Gmail Offline is a Chrome Web Store app that helps you read, respond to, organize and archive email when you don’t have an internet connection.
Google also says they’ll be rolling out Google Calendar and Google Docs offline within the next week.
You can read more about it here.
I like that Google is adding these options as it makes Gmail more user friendly and allows for reading and writing offline.
How does this impact you and your email use? Are you a Gmail user?
