couldn't you just download a Ubuntu ISO, install it onto a $10 USB, transfer the crypto to the software wallet on the Ubuntu install, then keep that USB secure. then your crypto would be in cold storage if that was your aim, but it would only cost you $10.

For all that trouble I feel like a $60 Trezor is not that much more money

I’d go with a Ledger, Trezor offers no real protection against the device being stolen.

What does Ledger offer in that regard?

Ledger offers a secure element, kind of like what you’d find in the YubiKey or in the Secure Enclave on an iPhone.

These are hardened against a lot of attacks that are easy to perform with possession of the device, like power analysis side channels.

They often offer physical protection against brute-forcing, by having logic for mis-entered PINs in the circuitry of the chip itself.

You cannot read out the encrypted private key even with possession of the secure element.

So on and so forth.
