It’s been a few days now, and I have a bit more to add.
This thing is fantastically loud. It also feels very nice to type on once you get used to it. There is also a slight effect of not being able to type on normal keyboards, but it’s not nearly as bad as the kinesis concave one.
A few annoying things have come up while using emacs, though. C-x C-f is a little harder to press, since X and F are farther apart.
