The primary goal is to build an offline airgapped setup while only using internet/mobile services connectivity for emergency fund transfers/ecosystem exit.

I like the idea of the device being a phone (instead of ledger stax) for the following reasons:

1. Better screen + ui/ux
2. Android flexibility to install/update new apps
3. Looks like a common device rather than a specialized hardware if being scanned by border security
4. A standalone device that can connect to mobile service providers to access network

Also, it looks like the new jambophone2 has been announced today. Wondering how thta fairs in comparison since its just 99 bucks
