Someone shared on Trisquel's forums a direct email communication with Purism revealing the way the company avoids being fully transparent about the fact that their device does not offer better privacy when used *as a phone* — it has privacy advantages only when the phone functionality is completely turned off, in which case the questioner claims it is nothing more than a pocket (or even stationary) PC.

Exactly -- the device is addressing all of the binary blob drivers and proprietary hardware that a rational person would view as insecure, and gives us the ability to physically turn that shit off when we don't want it doing whatever it does. The other option is to carry a phone and a PDA -- that might even be a safer solution -- but having the hardware switches is sort of a happy medium in my thinking.
