See my posts above, it doesn't work in Chrome 
But fun aside, once you got the plugin for your browser installed, it works quite well. I don't have it set up for a long time, but setting up the device is easy and the process is very well described. I've done a few transactions already and everything worked flawlessly.
The source code is available (here) and so far no vulnerabilities have been reported AFAIK. The device uses BIP32 so hopefully as time passes more and more wallets will support the TREZOR.
