Just added the Trezor Safe 5 to our catalog and updated and added new documentation for how to utilize it with free software. The one negative about the Trezor devices is that they direct users to install the Tezsor Suite which is propritary software and undermines ones security. Entertainingly the firmware is released under free software licenses and you can (if you know how) get the Trezors (or some models) to work without the proprietary components utilizing software that ships with at least some distributions. For instance on Debian it'll work with Feather Wallet (Monero) which is really awesomely now in the backports repository (and free software to boot) and the Electrum Bitcoin Wallet. These are the two that tend to be better supported on GNU/Linux and included in distributions to one degree or another and in some instances have some amount of "out of the box" support (thanks to the free software aspects).
