Gmail Goes Offline.!!
Just Two days Before One More Feature was Added In Gmail i.e. You Can Access Your Mails While You Are Offline.!!!
Gmail implemented it successfully in its Gmail Labs and now its open to worldwide Gmail users. Gmail Offline Feature uses Gears which will download a local cache of your mail. Time for which user is connected to internet, cache is synchronized with Gmail Server's. Now if user gets disconnected from the internet, Gmail uses the data stored in the hard drive. While in the Offline mode we can even label the mails and also send a mail which gets sended when the user is connected to the internet next time.
With this Gmail targets mainly users who have less connection speed or the users who experiencing frequent connection Lost.
