You're right. The words "cheap" and "Chinese" are sort of red flags that maybe you won't find such nice USB headers and will have power distribution problems or noise on the audio ports or heat issues or bad liquid capacitors or any variety of cheap hardware problems.
While you're technically correct today - on the other hand, a $50 dual core computer on a stick isn't a bad value proposition. Would you really want to put a $200 usb-sized computer through the wash by accident? Or take it travelling and have it filled with sand?
Also, I'm old enough to remember when "made in japan" was synonymous with the same sorts of quality issues that "made in china" represents today. Now, half my tech items are over-priced and underpowered sony products.
He's being sarcastic. Raspberry Pi had all the hardware problems he referred to.
