If you someone who frequently flies or has limited access to the internet at times, this might be a good thing for you. Google has released a Chrome web app called Gmail Offline which does just that. You can now access some of the popular Google services like Gmail and Calendar even without a net connection.
“Google Calendar and Google Docs let you seamlessly transition between on- and offline modes. When you’re offline in Google Calendar, you can view events from your calendars and RSVP to appointments. With Google Docs you can view documents and spreadsheets when you don’t have a connection. Offline editing isn’t ready yet, but we know it’s important to many of you, and we’re working hard to make it a reality.
