If all the node boards were interchangeable I could almost accept the high price - the idea of stocking up on a couple of spare node boards for a quick and easy repair with no down time has got to have a value, especially for an operator/location. And if they were repairable, even better. That would be clever design.
But they’re not interchangeable, they’re not repairable and they’re ridiculously expensive. Stern still argue operators and location pinball are the most important segment of the market. With crap like this you wouldn’t know it.
When you’ve got no competition you don’t need to worry about improving the end user experience- you just try to maximize profit by reducing costs.
