So there you have it - ads are very likely going to be part of Gmail soon. After all, it seems almost silly to not monetize a core app with an absolutely massive install base - between 500 million and a billion.
Oh, how the other half live.
That line: "it seems almost silly not to monetize [it]" is bone-chilling to someone on iOS like myself. Everything most of us do is about limiting ads as much as possible, and all you have to do is pay the developer a few $ in order to achieve it.
To someone like me, Android represents a hideous dystopian future living in the present.
