Personally, I value both. I want all the modern so-called 'tamper proof' features that an OS has, but I also want myself to be in control of all of them. I am fine with switching them on so that only signed code is executed and let the OS maker handle certificate revocation and all that. But if I want to use it as a dev box, I also want the option to turn it off.

Ditto for customization - I want the ability to tweak and change tuning/configuration parameters for performance reasons, for productivity reasons, for aesthetic reasons, but I also want a 'force defaults' and/or disable customizations option for when I'm setting up the computer for a family member, etc.
