Engadget - The official Gmail app: it's fine, really it is, but if you want unified inbox support, productivity features or the ability to pull emails from more than one place, you're left wanting. This sort of limitation can be found across Google's stable of apps, from messaging to the calendar and camera interface. We've trawled Google Play to find software alternatives that -- dare we say it -- do a better job, at least with certain tasks. So please, whip out your phone and give them a go.
Nice list, but they miss to add alternative to google translate, google maps, google hangout :P
