Well.. It's really just the internet that allows hackers to work their ways. Without the internet, every piece of hardware would be safe if never got into the wrong hands - which now a days is easy and hard (depending on you're attention span....)
A lot of my highly important information I keep on a small yet handy PDA and I NEVER connect it via WiFi. That way its safe and mine and no one will get it, and it isn't paper..
