iPad Pro

I have an idea of how I could get around it in that purchases where it's basically a yearly purchase that is effectively a paid upgrade. And you know, look at how predominant, persistent and invasive subscription type services are in enterprise. So any basic change in UI, you'd have to give all the users free. Where does it, at what point is the iPad Pro not totally crippled by the fact that no one can make money making professional great software on it? Unless they're doing some kind of weird cloud subscription, which is what you're suggesting.
