Interesting. With Ledger and Trezor being practically the only ones out there, there are other companies bound to compete and create something accessible for other types of users and crypto enthusiasts. Trezor offers a certain kind of security, and Ledger offers the simplified version of such a security. There should be more than just two wallets out there and as updates are made, upgrades are made, and new wallets are created, it's bound to appeal to those who were previously sceptical if for the very reason that having a wallet seemed too complicated.
