- will your driver and/or mining software be open source?
- In the case where GPL code is used, will you respect the license and post your modifications? You know, unlike your competitors (I'm looking at you bitmain and lketc ).
- will you make your circuit schematic docs open source - or at least available as PDF?
If the answer to the above questions is 'no' how exactly do you expect customers to maintain/repair your products?
One more question: how long do you plan to support the product e.g. firmware updates for bug fixes, new miner software versions, and performance improvements?
