Product differentiation? Why not let me decide what OS works for me, I am sure if ipads/ipad pros ran 2 or 3 different OS, then you would see more sales as folks can see how a product fits into their needs, Apple is prescribing that everyone needs the same product, this reminds me of what cars were like in East Germany in the period post WW2, you only had the Trabant... one car no matter how much you wanted a VW, you had to make do with a Trabby, in all honesty, Apple Inc is extremely communist, they sell the pc equivalent of a trabant, laptops that only come with factory fitted parts, or ipads that cannot be upgraded or run a better OS/different OS.. Apple is more North Korea than North Dakota...
