FWIW, the wood thing does not really seem like a selling point, and also most likely drives the price up more than a plastic case would.
I like the concept of it though and plan to research the APIs a bit more and then will likely order a couple.
White (plastic or painted metal) is something that could probably blend in to almost any space.
(It also shows misplaced priorities, in my opinion, when the homepage mentions the Janka hardness of the wood. I don't care how hard the button is because I'm just pressing it with my finger...)
That also just reminded me of another big downside to wood: all the dogs I've ever owned have been really interested in chewing on wooden objects left around the house, even if they were otherwise perfectly respectful of everything else. I've lost quite a few shoe-polish brushes over the years.
An aluminum one would be interesting though.
