So, as Google mines all our data, to make money..
..would it wind them up if people only uploaded encrypted files (Truecrypt containers)? What's the maximum file-size?
Can the pl0d go to court and get Google to give over all your files? Like, if they suspect you're involved in crime, or if one of them fancies you (and you are female).
I'm sure they'd have all those UK uncut protestors' details, for example. We're all geeks, but will the general public realise these (potential) dangers?
If we have to use their web interface for managing files, it will be a PAIN IN THE ASS.
In conclusion, this service is only useful for backup
