If I knew that I could always recover my money with my seed, then I wouldn't be afraid to try out the trezor.
Yes, you can always recover your money with the 24 word seed. If your Trezor somehow gets broken, you can get a new one and import the "old" 24 word seed into the new one.
Alternatively, if the firmware somehow becomes incompatible, you can convert your Trezor 24 word seed to a 25 word seed compatible with monero-wallet-cli using this guide. Thus, after conversion, you'd be able to restore your coins with the monero-wallet-cli using the following command:
Linux and Mac OS X
./monero-wallet-cli --restore-deterministic-wallet
This should be done from the terminal from the directory of monero-wallet-cli itself.
Windows:
monero-wallet-cli.exe --restore-deterministic-wallet
This should be done from the command window from the directory of monero-wallet-cli itself.
