Really glad they went with NFC to interact between the phone and hardware device. I've said this before and I think NFC will be the bridge that makes it easy for normies to onboard to Bitcoin through LN, as I think LN payments done in-person will be mostly over NFC instead of QR codes.

Alongside designing the hardware, we’re also diving into how we’ll build an intuitive, forgiving recovery experience that people can use when they lose their phone, hardware wallet, or both. With our underlying use of a multisignature wallet, people will be able to recover easily from losing just one item, but there are some big design and implementation questions on the best ways to get there and how to handle loss of more than one item.
My thought after reading this is that with NFC you might be able to create a multisig wallet abnormally easily. I don't know much about NFC but if you have the devices together and they can communicate with each other, perhaps the computer can address the devices as a group which would make multisig as easy as singlesig.
