Actually quite the opposite , there are still way more android phones out there than iPhones. Apple is a premium brand by most standards. And we’re arent comparing Dells, I’m talking Apple. And finally, Apple is not going to lose revenue for two reasons...first they raised prices, second , they are going all in on services and ecosystem. They don’t care if you have a 5 year old phone as long as you are in the ecosystem which brings them money as they continue to offer new iCloud services, music, movies, news, rentals, etc etc. Think about the bigger picture.
The point about Dell is that computer parts are continuously getting cheaper. You don't have Apple to thank for a MacBook Pro being cheaper today than the equivalent PowerBook 15 or 20 years ago; rather, you have parts suppliers to thank, which is easy to see because prices fell industrywide. Thus, being cheaper is not a courtesy, but an obligation on Apple's part. Apple is actually screwing the customer in that they could have made their hardware even cheaper, in line with what other manufacturers have done due to decreasing part costs, but they didn't. Now you might argue Apple uses more expensive parts, and that is true to an extent, but not enough to explain the price difference -- after all, they're using the same Intel chips and chipsets as everyone else, the same GPUs, and the same type of RAM, and these account for a significant chunk of the computer's price. The main differentiator are the faster SSDs (and boy do we pay very dearly for that, given the price of SSD capacity upgrades), as well as the touchbar which many feel is gimmicky -- and also, as I pointed out before, the price increased by $300 to $400 when the touchbar models were introduced, and as much as you may love it, can you honestly claim it's worth that much? There's the screen, but currently many competitors offer screens with a similar level of quality for their top-end laptops. Personally I love the new keyboard, but again I'm sure most will disagree, and never mind the reliability issues. The trackpad is great, but how much does it really contribute to the laptop's price?
As for services, sure, you can make money off a 5 year old phone. It's still a 5 year old phone though, and at that point the customer is seriously looking at an upgrade. If Apple pricing is now out of reach for this customer, not only did Apple lose a large sale in the hardware division, but also many smaller future sales in the services division. If you think about it, this is an even stronger reason for Apple to accept slightly smaller margins for their hardware, so they can keep milking the customer for the lifetime of the device. Unfortunately it looks like Apple is getting a little shortsighted. These price increases may help make them beat their records for another quarter or maybe even a year, but after that I'm afraid they're going to go downhill, and fast.
