I have one, but it's in a drawer now because I was finding it too difficult to switch between it and a normal laptop keyboard. I want a split keyboard that has all the keys in the same places, so muscle memory doesn't need to adapt. I touch type, so the same fingers just need to find the same keys in the same relative positions. Mainlander does not do that, and I can't find the layout or top view zoomable photos for this one :-/
