I find it ... philosophically interesting ... that these boards HAVE been designed (even if poorly.) The stereotype and expectation for the cheap boards is that they'll all be copies of some (probably reasonable) design from somewhere else. And yet, we see boards with no bypass caps, boards with extra crystal caps on a resonator, boards with no input/output caps on the regulator, a variety of usb/serial converter chips/circuits, a variety of extra connector footprints, and so on. In a way, it's very encouraging...
