This is a pretty nice write up and I can tell you took some time doing so, appreciated. One thing that I would add or mention with your write up..I believe mycelium works fine with android devices, but I don't think that it works with iPhones.  I used to have it on the iPhone and they simply stopped supporting the app.  Luckily I was able to get my bitcoin off of it, but just a heads up, you might want to build that note in to your write up.  Otherwise, good stuff.
