GPG is cool too but what about just a Secp256k1 signature like the original trezor does? You know, on the "sign and verify" tab of
wallet.trezor.io?
Oh, I thought you were talking about GPG all the time, my bad. Touchscreen works great, I don't have to use a lot of pressure - it feels just like a smartphone. On the video you might notice some black lines, this issue has been already reported
here. My hand was shaking a bit, I'm not used to recording using only one hand. Before making this video, I have changed my PIN and decided to use different passphrase. It was difficult for me to type in a passphrase because I usually hold the device in my hand, it is much more comfortable.
