Google has added a notable addition to its line of "Go" edition apps -- the lightweight apps designed primarily for emerging markets -- with the launch of Gmail Go. From a report: The app, like others in the Go line, takes up less storage space on users' smartphones and makes better use of mobile data compared with the regular version of Gmail. The app also offers standard Gmail features like multiple account support, conversation view, attachments, and push notifications for new messages. It also prioritizes messages from friends and family first, while categorizing promotional and social emails in separate tabs, as Gmail does. But like other Go apps, Gmail Go doesn't consume as much storage space on the device. In fact, according to numerous reports, Gmail Go clocked in at a 9.51 MB download, and takes up roughly 25 MB of space on a device, compared with Gmail's 20.66 MB download, and 47 MB storage space.
