noticed it is now possible to sign messages with the trezor 
Amazing! I'm going to begin tying my online identity to my trezor then.

Weird, just tried signing a message using myTrezor in Firefox and nothing happened. What's supposed to happen when you click "sign" ?
Tried with another account and it worked. So, when it DIDN'T work, I had entered a "blank" password and thus entered an unused account... when I used the receiving Bitcoin address to sign a message (which hadn't yet received any bitcoins) nothing happened when I clicked "sign"
Yep i had to send 0.00006 bitcoins to the address that I used to sign that message before it would work.
Also there is a rather short limit to the longest transaction it can sign. That makes its functionality for doing things like signing contracts limited. I suppose you could make a hash of a contract and sign that hash though. Probably worth it for the security that you would gain from using a trezor instead of keeping the keys to your online identity on a computer. I wonder if people will be able to to get used to and accept signing a hash of a contract rather than signing the contract its self.
