I made up the numbers as an example. It doesn't really matter, my point is that Apple's old devices, be it iPhone or Mac, still have value years later. So even when people are fishing the old stuff from the bargain bin sites, Apple is still making money off of them. As a result, Apple doesn't need to compete with the $400 Dell because people will still be buying the 5-year-old MacBook Air from the bargain site and with it, buying app/iCloud subscriptions.
