A client base that holds a brand's feet to the fire. Once you have a client base that views their brand of choice like it can do no wrong and bends into a pretzel when explaining it's shortcomings, that's when you have a brand that moves slow to be on the cutting edge.
The Apple ecosystem indeed has fan boys, but look at the animosity they've gotten for...
1.) MacBook Pro touch bar.
2.) MacBook notch.
3.) iPhone dynamic island.
4.) M4 series Mac Mini power button placement.
5.) Lack of an extra internal SSD slot in makes for 3rd party SSD DIY upgrades.
6.) Pre-Apple Silicon when iMacs lost RAM upgradability.
7.) Ridiculously expensive RAM and internal SSD upgrades (with RAM you might argue system-on-chip, but the SSD thing? No, sorry, uh-uh, I think that's just gouging).
8.) Until the M4 series Macs, a LONG time with 8-gig RAM as the default on multiple Macs.
Just look at how many Apple users on this forum say how they see no need in a foldable or flip. We all know full well most of them will be jumping on one as soon as Apple will release one. All under the guise of, "Well Apple did it right."
Don't be so such. I don't want a foldable iPhone because I don't like the idea of a hinge, I always use a durable protective case (these things get dropped), I don't want something double the thickness in my pocket, and my iPhone 12 Pro Max fits in a breast pocket and sticks out the top but it's a decent working arrangement for me. I also saw a price for an Android gadget that I think basically folded your phone into a small tablet, and...nah.
For that matter, I'm not breathless with anticipate over what Apple Intelligence can do for me. I hav more of a 'Meh, wait and see' attitude.
Apple has external competition (e.g.: Android, Windows PCs) but not internal competition (within its own iOS and Mac Apple ecosystem), unlike Android phone/tablet and Windows PC vendors, who compete with each other. Otherwise, somebody else would make a Mac with 1 or 2 internal SSD slots. Therefore it's harder to hold Apple's feet to the fire.
Imagine if you couldn't abandon Dell without abandoning the Windows platform, or Samsung without abandoning Android.
