Would be cool if a Hardware Wallet maker decides to build a modular Hardware Wallet so that we do not need to upgrade by purchasing new Hardware Wallets but simply by upgrading parts, similarly to a PC. Need more space? Need a better processor? Need a new display? Open it up and switch the components all by yourself.
It is a very very interesting idea. Reminds me idea behind Fairphone - smartphone which components could be easily replaced by the user. Ask them, propose the new product…
Unfortunately trend to minimize everything made it difficult to reassemble and even recycle electronic devices.
