I do recommend cold wallets, robust ones, like Armory
If you get a "malicious"/"bug" Armory, how can you protect your bitcoins? With your "
robust"?
Armory is open source with a good dev team. They have a correct security mindset (BIP10 is written by Alan). The cold Armory wallet put no trust in the hot one.
Anyway, we already have BIP10. If one wants to use QR code with BIP10, it's straightforward.
