From what I've seen of the Snowden leaks, there's nowhere to really get away from the NSA. They have their hands in every major manufacturer. They have cables that can steal your info, they can the most complex malware written to date. Apart from completely removing your entire digital life, I don't see a way to stay out from under their eye.
If that were true, there wouldn't be Snowden leaks nor would there be Ed Snowden himself.
