Apple has been know to contradict itself to market whatever it believer to convince consumers of it vision. If Apple believed in the digital pop-up keyboard then why does the iPad Pro have a physical keyboard. It is still far more comfortable and efficient to use a physical keyboard, that is why. This same convincing was used with the stylus and along came the “pencil.”
I have an iPad Pro with the keyboard and pencil, would I want a similar and additional input options on the iPhone, sure I would. Competitors offer a stylus that have made it popular for fine detailed input and comfort compared to using a finger, however it does not mean that using these alternative means of data/text entry and manipulation is a bad thing. If Apple reversed course on its initial decision, people will just forget the hypocrisy as this is Apple and their will just convince you that this is a new and improved alternate way to data entry and the technology just did not exist back then or not good enough, we have heard it time and time again.
One of the reasons for a non-swappable battery was to make the device thinner and reduce complexity, yet the integrated battery life on the iPhone is terrible and Apples own solution is a silicone care with a “hump” battery to extend usage and the numerious their-party solutions. Is this solution simple, nope. Has internal batteries gotten larger, just marginally as the space is shared with other components.
When the original iPhone was released, it taken three main tasks completed on a computer and went truly mobile, this was done in a near seamless manner with simplicity in-mind and we had the brilliant presenter and presentation of Steve Jobs that just made the audience believer anything is possible on this little device in the palm of your hands. It was the AppStore that slingshot iOS more than anything. As far as competitors go, tech companies always mimick concepts from its competition as they reduce risk in the market to what the consumer will accept to make a product successful. Basically Apple taken some of the risk and it paid-off, and their have been fortunate not to have any major failures in that 10+ year span. I give them credit for that, I am not here to insult them or place them on a pedestal, I prefer to be honest with myself relating to these matters
