I disagree. Apple outsources too. If you need a production line, it doesn&#x27;t matter too much who builds it. It takes time to build it anyhow.<p>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.<p>There is big differences, but this is not it. You could claim Apple is less agile, as they lack mass customization of hardware.
