OK, but where do you store your key, if not on hardware? That's what I don't get. And while not storing it on the exchanges makes sense, it also seems to remove some flexibility. I could store all my (dollar) money at home, but it's a lot more convenient and safe in the bank. And the bank doesn't lose it like the Bitcoin exchanges do.
You can store it on hardware if you want, but you open yourself up to being hacked if that hardware is connected to the web, or you can print out a paper wallet, essentially a piece of paper with the key on it, if you lose that piece of paper you lose your money, much like cash.
You don't need to store your bitcoin at exchanges, that is what most people have are hard time with, storing it at exchanges greatly increases your risk and is what is getting the bad press.
Here's another article on how coins are 'mined' and how the integrity of the transactions are maintained. I am by no means an expert on this but know enough to be dangerous. Check out the link.
