This worries me more than the malware.

I don't own an e-book reader because books that I purchased could be deleted without my consent.

This is surprising. Does anyone know if Google can actually do this? Maybe provide a reference.

They said they could and would do it, just as Apple and Microsoft have said they could do it.

Nokia can't do it, but the people don't like their Symbian UI. Those are the priorities I guess.
