I was wondering why ColdCard didn't make your list as I've heard many good things about it, and then I ended up slam-bang in the middle of your debate with nvK on licensing lol. Objectively-speaking (completely disregarding any licensing issues), what do you think of the Mk4?
It was in my list when it was open source wallet, then they decided to change source code to common clause + mit, that is not allowing anyone to use their code.
EVerything started after Foundation Passport wallet came out that used thier code, but it is superior device in every way, with open source hardware and software.
ColdCard is still ok hardware wallet to use, but I just don't like direction it is going and their owner NVK is ego freak and hypocrite.
Of all the methods you posted, is there one that allows for partially signed transactions (like ColdCard)? Not being able to sign transactions offline is a major issue for me.
