You forgot one thing. The range between $649 to $849 was for the top of the line. In fact the iPhone 4s was still in play at $400's. So yes, they have largely increased the pricing while the phones got larger

!!!!
Anyone with unclouded brains can easily see this. Apple since SJ died has been playing prices against their customers while removing value out of their products across the board.
1) Not updating Mac mini for years and years,
2) Not updating Macbook Air for years and years.
3) Not updating the iMac line regularly.
4) Simples things like removing the Target Display Mode (TDM) from the iMac line. As a owner of a MacBook Pro I was going to buy an iMac for my kids and when found that this feature was removed I simply did not.
5) No updates to Mac Pro lines for years and years.
6) Swapping ports in the Macbook Pro line for expensive dongles and cables.
7) Airport line could be made a really interesting connected home solution ... but they ... well they did not updated it.
8) iWorks simply stalled. Actually they removed features (value) from it.
Meanwhile ....
1) iPhones got better yet significantely more expensive (nice product)
2) Apple Watch appeared and got better. Waiting to get really popular to hike the prices probably (nice product). They seam to be getting more expensive.
3) iOS got better yet more expensive die to devices price increase.
4) iPad got better yet significantely more expensive.
5) They have built huge palace for themselves. And a loads of mini palaces, sorry stores, across the globe.
6) Customer support got much better.
There is little innovation in making things better yet more expensive. If better and more expensive was the rule of progress how much we would be paying now for a computer? $200.000?
iPhone won peoples hearts because it was actually better than the Nokia Comunicators, Palm's ... so on and so forth yet the same or less expensive. And was way, way more advanced than the "$200" smartphones of the time. Now that is value!!!! That is what put Apple in the position they are now!!! TC strategy is simply eroding this perception that inspired rags to richies.
