x86 and Unix are insanely complex too and a big part of that complexity has to do with backward compatibility. I've scanned through the specs and I haven't seen any complexity just for the sake of it. Care to point out any specifics? Also note that some of the added complexity is to support new features, such as power provider/consumer switching and power safety. As for the substandard Chinese grade products, they've always done that and will continue to do it. Bulk of existing USB chargers you find have horrible ripples and have power factors that seem to have been engineered to be embarrassingly low.
