Trazor is safe windows is a issue .. And use a air gaped system to sign cold wallet transactins the signing key can then be posted online.....
Its very easy to do.
I have just looked at various reviews of the Trezor, and it indeed seems to offer a decent level of security, but I personally don't like the fact that you depend on a connection between you and their (server) website in order to use your Trezor device. But I also read that it supports Multibit and Electrum. Does that mean if I use my Trezor device in combination with these clients, that I can have it work without it needing to connect to the Trezor servers?
I use my Trezors without ever connecting to the Trezor servers. You can even initialize your Trezor OFFLINE pretty easily once you learn how its done. In addition I use Electrum and only onion servers to maintain maximum privacy. You will never regret getting a Trezor.
In fact after reading through this thread I just gave one of my Trezors a kiss. joking - LOL!
It's good to hear that it's just an optional service which requires connecting to their servers. I will purchase myself one as well. Unfortunately the white version takes months to ship. I'll probably go for the grey version even though it's $20 more expensive. It's the only color in stock. Right now I store my wallet.dat files in multiple USB drives where once I import them, I need to enter the passphrase. Exactly there lies the risk as a keylogger can easily pick up my password and cause severe damage. I must avoid that.
