Gmail for Android received a really nice update last week. It came with an awesome card style UI, but there is much more hiding behind that beautiful style. Google has also included some coding into Gmail v4.6 that will not make many of you happy, because it seems the app will be getting ads very soon. The app has managed to stay ad-less until now, but we must realize Google lives off advertising. It's the main reason why we get most of their services for free (or very cheap).
