What do you guys think about Armory? I heard that it is one of the most secure but haven't actually tried it out myself. There are many options available on the market so it's hard to pick one. Logic says the most secure is the best.

In terms of storage, you wouldn't want to keep it on your desktop because it could get hacked into quite easily. There are plenty of scripts nowadays the even use your CPU to mine, let alone get into your wallet. You should keep it cold. Disconnect it from the internet.
