I have now been using trezor as cold storage. I like how it is almost like a hybrid wallet, where you don't have to sweep the entire thing when you want to spend.
The one downside is that you have to rely on their API (I think). The backend of the website was down the other night, so none of us had access to our coins in the meantime (unless you wanted to use the recovery seed on a different wallet)
I personally do not trust trezor. You should have 100% access to your private key at any time. If their website goes down then you need to have a way to recover the private keys
Well, use your backup! :-P
It's standard-conforming, following the BIP0038 scheme.
Either put it into another Trezor, or in your case, any other BIP0038 client.
