The point is that the _aim_ is to ship a high-sec device. Normal-spec devices will be available from other sources.
We don't know what the final spec of the Edge will be, and the CPU hasn't been chosen. However, it will be able to use parts that are available for a small production run (40k) but not a large one (4 million etc).
Edge has to be relatively expensive because costs are amortized over 40,000 units rather than 40,000,000.
