How much is only the raw cost of the display (say 15"), and how much would it go down with scale? It doesn't look like you guys are skimping on the other parts

How much is only the raw cost of the display (say 15"), and how much would it go down with scale? It doesn't look like you guys are skimping on the other parts of the device, which I think a mass-consumer device could (should) do. Arguing the other way: I think the other problem is that such a device doesn't make more money. Amazon can sell echos at a loss because it knows it lifts its other revenue streams.
