People still don't encrypt their email (at least the overwhelming majority of them). The convenience of ubiquitous mail access across multiple devices has made encryption even less likely (i.e. do you carry your private key with you everywhere?).

I doubt consumers will care much about the privacy of their data in "the cloud".

I can only assume that companies with data that needs to be private will take appropriate steps to protect it, but as we've seen with lost laptops, usb drives, etc., they don't always take the best of precautions.
