I haven't found anyone else who uses it surprisingly, but Gmail Offline (Chrome App). I use it when online. It has amazing keyboard shortcuts (faster than Gmail proper), and then of course you get the perk that the data is offline once you hit the train. Actually, I think the keyboard shortcuts might be the only reason I use it...
