I came to say the same thing. Ortholinear (grid) or staggered columnar keyboards would appeal to an extremely small but passionate group of ergo keyboard users. Given that the alternative for folks who use this kind of layout is to carry around a separate $150-400[1] keyboard I think at least a few people would be willing to pay a hefty premium for a laptop with a customizable keyboard.
