Great article although I'd say you should have touched on encryption.
It's essential to encrypt everything important as if it gets stolen, or seized, unless it's encrypted you may be in for a big mess, especially if you dabble in illegal activities or you simply are a target.
By a target I mean someone the government deems a threat or dislikes.
If that's the case they may try to find any reason to charge you and get rid of you, be it you accidentally viewing or downloading something copyrighted or downright illegal, or if it's using what you have saved on your computer to try to say you did something illegal or are evading taxes even if you aren't.
It only takes an hour, just Full-Disk Encrypt your computer with a good algorithm and at least 20characters, I'd recommend Veracrypt.
