I was feeling inspired to write this morning after looking through a lot of this type of article and noticing they all omitted kind of important information. This includes all of the basics, and the stuff I thought was under-discussed, for example: AirDrop's privacy problems, and the importance of security patches in this specific scenario.
I hope someone finds this useful, and if I'm still missing anything or could explain something better, please let me know!
