I am also using Armory as my Bitcoin client and what i like about it most is the ability to make so called 'paper backups' (printing your wallet key on paper). One could ask whether it would be required to print countless times for each new adress you are generating. In fact, your Armory wallet is deterministic, that means all future adresses which are to be generated are predictable. So there are no annoying backups anymore, one single backup after creating the wallet and keeping it in a safe place, whether it be digital or physical, is sufficient.
