Thank you, Sir!
Great job, pretty cool you took the time for it. Not surprising is that people buy matching colors (the diagonal is about a magnitude higher than the rest in the according row/column), and that people like black. What I find surprising is that there are "only" 1500 keyboards ordered so far, that's a really tiny number in the phone segment, I wonder: I it even economically viable for you? (I hope so...). Also surprising to me is that Alumide has such a comparingly low fraction, we are already in the premium segment with the keyboard, so looks like people really just strongly prefer black.
So thanks again for taking the time to put this together, I found it very valuable and I am very much looking forward to being able to order one myself soon (hopefully an assembled one ^^).
Meanwhile I'd be curious in statistics for the backplate. Let me guess: Place 1: Steel Black, 2: Carbon Black, 3: Steel Gray?
