Zxq,
i pretty much agree with all points you mentioned .
Re : privacy - my employer actively utilizes amazon as a distribution layer only.
From consumer perspective , i was thinking to use it for 2 reasons

To have a single and easily accessible destination for junk files. And as a backup for important files.
I do agree that Google as a backup is far from ideal (exactly  for reasons you stated). Yet been an gmail and android user already it seems convenient.

Also, I didn't mention this because I thought it was obvious, but you don't exactly "mount" the Google Drive. Its basically like a feature-deprived version of Dropbox with an even worse privacy policy that only integrates with Google products. It is absolutely not available offline -- and actual syncing has to be a deliberate choice, every time, so actually saving to a local drive you own for real is not automatic or even reasonably hassle-free. So this sort of sucks.

If you've got no experience whatever with this sort of thing these are probably the points you are curious about from a consumer's point of view.
