Really? This is a problem?

From Gizmodo:

"Apple's problem is that their products are so good, people aren't upgrading fast enough."

There's nothing about this statement that makes sense. Anyone who understands the current tech landscape knows that it's all about the ecosystem. Regardless of when they upgrade, they will upgrade. Apple's ecosystem lock-in is so much more all encompassing at this point that once you're in there's no reason to leave.

Also, I can't think of a better reason to buy from the same company than 'this lasted way longer than I thought it would'.

How much of Samsung's revenue is driven by Apple products?

With rumors surfacing that Apple is shifting chip manufacturing and potentially component purchases away from Samsung, the company many consider to be their key rival, it makes me wonder: How much does Samsung make off of Apple's massive quantities of parts for their devices? Apple is so big they are often compared to groups of companies or the entire US economy, but I wonder what kind of hit a business takes when Apple decides to go elsewhere.
