Would I be able to recover coins if Trezor went out of business? I'm considering a Trezor wallet. I've read through their info about recovering if I lose the device or forget my PIN. What if the company were to go out of business. Would I still be able to recover my coins?
Yes. Trezor uses BIP39 and is compatible with any other wallet  that would. You can in fact import your seed into electrum, though this to some extent defeats the purpose of having a hardware wallet.
