@jackg - I have ordered a webcam for future paper wallets, so I can use that on my air-gapped machine.
Yes I'm considering using Electrum or Mycelium for android, for moving coins between paper wallets, just to make the process a bit easier.
I would say that Electrum seems a bit more secure than Mycelium, because Electrum uses SPV validation and Mycelium uses central validation.
I still need to trust the trusted list from Electrum nodes (SPV).
