I totally get the offline laptop thing, I did exactly that for my earliest cold storage. But with what is coming to SeedSigner, SpecterDIY, Krux and Kern, these microcontroller projects are going to offer increasingly decisive advantages over the offline laptop approach. With support for dozens of development boards any association with bitcoin goes away so you sidestep all of the supply chain risk; you lose the attack surface of an entire microprocessor OS + app; you get better assurances wrt wireless comms being truly disabled; you can get something brand new still at a very low cost; the form factor is much easier to use and store; and the UX becomes much more intuitive and specialized like a HWW rather than a general purpose computer/OS. The advantages of FOSS + DIY are going to become undeniable.
