I won't even pay for a smart phone
Phil may prefer phone security to email, but I wasn't using my phone that much so I dumped the smart phone for a $5/mo pay-as-you-go phone, and even that I barely use. And I can't use encrypted email without all my friends using it too, and I work in IT and still can't figure out how to use PGP. The few times I tried encryption I promptly forgot my password and bricked my data. None of my friends are tech savvy or want to have to worry about it. Yes, encryption should be ubiquitous, but it must also be 100% transparent. If you think that's difficult or impossible, sorry but that's reality.
