Hi, jesse of keyboardio here.
As of this week, the editors actually have it more correct than our website. We'd been prototyping in wood. In between when the video was shot last month and when this got posted, we finally got our first "finalish" aluminum prototype made. The aluminum prototype was what we talked about publicly on Highway1 (highway1.io) demo day and what we hoped to launch publicly. Once we had it in hand, we discovered a bunch of reasons we're not going to go with aluminum for production. (Mostly, cost, Weight, looking too much like an Apple product, weight, and weight.) We went back to the drawing board and believe we've got techniques, technologies and costs for commercial manufacture of a milled wood enclosure. We've been at OSCON this week, but should get the website updated soonish.
