I have been to Asia. Not china specifically but South Korea and Japan.
When i was in South Korea (~2005-2006) the cell phones seemed way more advanced and better quality than the ones from the states. They were all watching TVs on their phones long before it was affordable for the normal person to do so here, i had one of the cheapest prepaid cell phones i could find and it still had a universal TV remote built in, Internet, and everything.
When you walked through some of the larger cities it just felt like technology wise they were far ahead of us. Huge clear screens on the sides of many of buildings, bullet trains, even the elevators seemed quicker and you could barely notice they moved. None of that weird feelings and squeaky sounds you often get here. Going up the Seoul tower was quick and you couldnt believe how fast it was going and how high up you were actually until you got out on the top and everyone was quite impressed.
Its my opinion they do have quality products. I had a hand built computer there that would rival anything i had seen here and it only cost me around 400 bucks, i sold my 750 dollar computer i brought from the states immediately for 300 bucks and it was only several months old because it just wasnt anywhere near as good as the one i got there.. my surround sound was spectacular. Pretty much all the electronics just seemed better.
Maybe we as Americans dont want to spend the money to import the more quality items, but that doesnt mean all products from other countries are crap. Im a proud American and i supported my country with honor, I joined up knowing there was a good chance of deployments into really nasty areas and did so without reservation. So im not knocking the US in any way, but some people are just so gung ho thinking Americans are best at everything and do everything better than other countries when its just not always the case.
