I disagree. Apple outsources too. If you need a production line, it doesn't matter too much who builds it. It takes time to build it anyhow. Both Apple and GM

I disagree. Apple outsources too. If you need a production line, it doesn't matter too much who builds it. It takes time to build it anyhow. Both Apple and GM still produce themselves their key components. Apple makes motherboards and operating systems. GM makes engines and has chassis production in house. There is big differences, but this is not it. You could claim Apple is less agile, as they lack mass customization of hardware.
