Any two-bit factory can make a cheap clone of an Apple product, and they provide no warranty, and there's really nowhere to return it if it doesn't work, and no QA testing, and if removing a voltage protection diode saves two cents, they'll remove it.
Quality is free, because everything else costs more. They aren't the stratospherically-priced arrogant company they used to be, although I think their desktop Mac pricing is ridiculous and they really out to put out a basic, three-slot, two-drive desktop computer that uses ordinary desktop parts and attaches to a plain old monitor. Dell sells such a thing for about $350. I'd happily pay Apple $600 for a similar, basic box.
