That's not what they were saying and the same can be said for those listed. But that they can cost the same as a Macbook Neo which arguably has significantly more technology in it.
Exactly and its just interesting to think about that such insane engineering has gone into a product that costs less than 4 wooden chairs. Yes it can be explained logically but its just an interesting thought.
A Moto G also has more technology than a Nakajima WPT-160 typewriter (which is still in production) but the latter costs more. Comparing "technology for the buck" across totally different kinds of products and markets sometimes just doesn't make any sense.
The point isn't for it to make sense necessarily, it's just simply an interesting thought and not one that always needs a logical answer in every case.
