Oh, and don't go anywhere that uses surveillance cameras or biometric identification, only use cash and don't go to an ATM near where you'll buy the device, leave your primary cell phone at home, don't check in to any location requiring your real name or ID, and if you have a car with a GPS in it, don't drive it. Reasonable, right?
