Google Drive for iOS, the reason why I love Google

They did not overmarket it, they did not say they were the best, they just made it.

Made what?

Made the coolest Document Editor on iOS.
It was ugly and limited two years ago. average one year ago.
They improved it step by step, versions after versions to finally provide a magnificent experience.
Mixing the benefits of the Cloud, Apps and fullweb.
Taking good ideas of box.net and Dropbox.
