I like the idea of the free VPN with the mail, these days I think so many of these apps can not only get your location, they can get your IP address and they can probably even get your computer's MAC address - if they get that then they can actually hook straight up to your network card and establish a direct link. The more of these you can protect, the better.

That Unix phone sounds excellent if you have the choice to switch the power to that part off.
