The claim that two manufacturers use some of the same sub assemblies = they are the same product is ignorant. A Ferrari F60 and some Fiats use some of the same sub assemblies. They are not the same product. A Corvette and a Chevy Cruze use some of the same sub assemblies. You will not confuse the two when you drive them.

I have spent 20 years working at computer manufacturers, including the Fruit company, PC clone companies, and peripheral manufacturers. I have seen the difference.
