@dthompson They demoed the PureBoot process at LibrePlanet, using the key, and it looks great. I have a Nitrokey Pro---which is all their key is, plus the extra LED---and they said it'd work with that.

I asked them two years ago at LP if they'd consider adding Trackpoint, and it wasn't something they were going to do at the time. That's going to be a major disappointment for me as well. But there are keyboards that have it built in (of course that doesn't help on the go).

@cwebber did you ever get a chance to find/use a USB-C dock?
