Sure there is. Apple does this kind of segmentation all the time. Retina came to the iPhone 4 and then included it in iPads 1.5 years later. Touch ID first came to the iPhone then to the iPad a year later. Apple Pencil was first introduced in the original iPad Pro then came to the 9.7" model 6 months later. The iPhone 7+ has dual cameras with optical zoom and faux depth of field blurring while the iPhone 7 only has a single lens digital zoom. AW Series 2 is water resistant and has GPS, Series 1 has neither.
That is not to say AR won't make it to lower tiered models. It will. But Apple -- if you look at the prototypes of each and camera placement -- won't include it this year. Apple rarely rolls out big features across all models at the same time. Apple isn't alone in this practice. Car manufactures, for example, routinely launch new features first in their flagship model and then push out to lower level models as the cost of the feature declines.
The reason they demoed ARKit on the iPad Pro was not to sell AR on the iPad Pro but to show developers that the iPad Pro can do the work of a laptop. Apple is invested in convincing the world that tablets are the next laptop.
Your rant is weak. The iPhone 4 was the only device to include the Retina display at the time simply because of the technology available at the time. The Retina display was new technology at the time. Apple was not able to introduce Retina display at a larger scale for other hand held devices , laptops and desktops at that time, simple.
Touch ID was simply due to supply, it was a new technology and they could not supply it in both iPhone and iPad at the time.
What’s your point about the Apple Pencil? It came out on the only pro iPad at the time. The screen on the iPad Pro line is different than other iPads.
Again. What’s your point about the iPhone 7 and 7 plus? The iPhone 7 is physically a larger phone. Thus it has more cameras a bigger screen, more ram and bigger battery. Or would you want Apple to magically squeeze all of that in a smaller phone and hope it works the same way as it does now?
The Apple Watch really? If you want one with water resistance and gps you get that model. If you don’t, get the other model.
You people seem to think Apple is constantly supplying us with old technology because another company may have introduced it first. Apple takes their time until they can have the hardware fined tuned to their spec. Plain and simple. This has been explained over and over by Apple as well as other tech sites out there. It is hard to introduce a brand new hardware technology across all devices because they either cannot meet the demand or they haven’t scaled the tech to suit that device yet. Even with oled displays, I’ve read many reports that Samsung could not supply, themselves, others and Apple because Apple quantities will be far too much. The iMac pro that is due to be released in December, why December? The hardware needed for it is not yet available. The Home Pod? Software is not ready. I could go on and on...
Apple goal is to release amazing devices people would want and enjoy, and make money. It makes 0 sense from a business stand point to hold back on technology that they have maturely developed and ready to ship, only to sell at a later date. If Apple has not released it, it’s simply because they cannot without negative consequences.
