Offline Gmail…!!!

I daily read Official Google Blog because Google provide new features in many services regularly. I was waiting for Offline mode in Gmail from long time. I was wondering because offline mode is available in Google Docs from long time. Last Tuesday, I logged in to my Google Reader and I saw first blog was Offline Gmail. I was very much happy and I immediately enable this Lab feature. I have embed YouTube video below. Watch it and take advantage of really cool Gmail Labs features.
