The iCloud meltdown preceded by the never ending follies of facebook probably told Google it was time to test their own stuff rather than wait for the storm to hit home. They are well ahead of the game with two factor authentication. Now if they could just add Zero Knowledge encryption techniques to their Google Drive they could be giving even more assurance they weren't out to market anything more about you than what is already public record.
I would love to have stuff backed up in the cloud, but as it is, the only cloud I trust is SpiderOak.
