It's got two independent halves that you can angle how you want, and put at actual shoulder width apart. It lacks the ortholinear layout, mechanical switches, and programmability of the Moonlander.
I went from the MS Natural Ergonomic Keyboard 4000 (which I used for years and loved) to the Freestyle Pro (same layout, but with mechanical switches and programmability) and it made a huge difference in my posture and shoulder tension.
It definitely takes up less space than the MS 4000, but it's still two pretty bulky halves that don't pack up to travel particularly easily.

I wonder if you could put an Arduino into the MS Sculpt and get the best of both worlds. Or maybe you could make an Arduino with a USB port and just have it remap keys on the fly.
