Re: As I have said a million times
Apple were lucky once: MS bailout before iPod.
They made TWO good non-tech decisions:
1:) Record label deals for iTunes made late comer to market iPod a success.
2:) Big or all you can eat Data for iPhones on Contract, when every other smart phone for EIGHT years previously had be crippled by per second and/or per M byte charging. Yes the bought in fingerworks GUI helped.
Apple (apart from failed Lisa, really Mac 1.0) has always entered ESTABLISHED markets and rarely innovated. An exception was the Newton, ironically one of the first portable ARM gadgets and killed off on Job's return to Apple.
Lisa was a clone of Xerox and other innnovations
OS X from NextStep itself based on BSD
iMac, MacBooks, iPod, iPhone, iPad, Apple Watch all followed proven established market entrants.
iPhone was commodity parts and phone subsystem merged with an ipod. Samsung SC6400 ARM made it possible. Capacitive screens 20 years old but not used as other OS needed stylus resolution and the "holy grail" since early 1980s had been handwriting recognition and annotation with a stylus, you need high resolution resistive screen. Apple with iPhone was aiming at content browsing, not content creation (hence no copy & paste) and high end consumer market. Previous smart phones (e.g. Nokia communicator) were corporate orientated / content creation/annotation and thus keyboards or resistive because of the very high data usage costs.
It's hard to see Apple replicating their only two really successful mass market entries, the iPod and iPhone, because those exploited non-techincal weaknesses in competitors (Content and Carrier data pricing).
So Apple will become more a niche product.
