This thread is full of people seeming to think they are smarter than Apple about this topic. By all means people, contact Apple, get a lucrative consulting gig, and straighten out the terrible mistake they have made. If you know better, go fix Apple.
Anyone who follows my posts know I'm no fanboy. But I think Apple leadership is smart enough to make the right mix of products to achieve their revenue goals. If something doesn't make sense to achieve those goals, I'm confident they would cut the product. We've seen recent examples of products- even popular ones like original HomePod and iMac 27"- getting culled because they were not hitting Apple revenue/profit margin targets. They very tangibly prove they are willing to kill products that disappoint or are not lucrative enough.
This mix- confusing or not to "99% (if not more)" is what they believe they need to offer to achieve what will probably be another quarter(s) of "record revenue." All of the armchair marketers that are smarter than Apple in this thread should go take over Apple and fix this awful situation.
Else, until their dumb mistakes start showing up in revenue shortcomings, it appears that what they are doing is working very well in the measure that matters most to them and their stockholders.
I fully grasp the consumer desire for simplified product lines. But Apple is a GIGANTIC company now. It would likely be hard to keep up with their own revenue records if they operated like it was 1997-2003 or so again. Take that to an extreme and that would kill off iPhone, iPad and Watch entirely... so they can be just a computer company... or computer + iPod company (with much simpler product mix).
Yes, I also grasp that many of "us" are wanting a single iPhone option and a single iPad option, etc. but Apple has grown way beyond that yielding as much revenue. There are not 4 new iPhone options this year because Apple knows everyone is going to buy the one best choice and ignore the other 3. They are all the best choice for some slice of the total iphone market.
