Thats a great read.
Before buying my first bitcoin in December of last year I spent probably about three months looking at types of wallets and ways to keep your stash secure. In the end I have opted for the brain/paper wallet methods for my main holding and use online exchanges such as blockchain/coinbase for very small amounts for trading/gambling/purchasing.
I think really security is the BIGGEST problem for most people (even someone like me who is NOT a programmer/hacker but IS very competent on computers) had to really rack my brain with all this security stuff.
Again great read... I am not sure what I would do if I somehow ended up with crazy amounts of bitcoins. I think I would be very paranoid
