It is possible to get a Banana Pi BPI-F3 at around $100. It has the same SoC in it.
The version with JH7110 is priced at $765, which seems not unreasonable for a quality case, screen, keyboard, battery and so forth. It underperforms for the price compared to a low end x86 laptop, but the money is not going into the CPU in either case.
A better assumption is that, as volume increases, they'll be able to make them cheaper. Fingers crossed for that.
