Harder for Tim Cook to get another
$120 million bonus if Apple were to continue selling low priced iPhones like the iPhone SE which had features similar to the at-the-time flagship iPhone 6s or by including a Lightning to 3.5 mm headphone jack adapter with the new iPhone
Apple seems to be better in the protecting my security area than Microsoft, Google, and the others, so I go with their products more often than not. I'm not loyal, I'm not a fan, I'm just selecting the least evil of the evil companies to deal with. You don't become a trillion dollar company by being loyal to fanboys. You become a trillion dollar company by putting profits first and foremost.
You become a profitable company by creating an appealing, innovative (maybe even revolutionary, as per the first Macs and iPhones IMO) product. You can become even more profitable by continuing to market appealing products and pricing to the newly created customer base, with incremental improvements to the original innovative product lines. Eventually that profit will decline if further significant innovation and improvements aren't forthcoming, or if pricing can't be matched to customer demand. I think Apple is near to reaching a plateau in its product lines - this is more apparent with its desktop/laptop offerings than with its iOS devices. Time will tell.
