iOS is entertainment and consumption platform just because you can't do anything serious with your greasy finger. You can edit text and graphics on Commodore 64 but almost can't on iPad Pro. There will be no CADs for $50000. One exception for this is music software (synthesizers, controllers) which are usable with touch screen but in this case OS (that is designed for entertainment and phone calls) is against them, i.e. no interoperability between apps, no real file system, bad external devices support (although sound subsystem is surprisingly good). Who wants to buy fart app or doodle drawer for $200? There's potential for games (it's possible to make or port RTS with great controls), but only on iPad connected to charger. Who wants this when there are PC and consoles? And what if you develop great new CelestialCraft&Conquer for 3 years, and users are willing to pay $50 for it, but then it's rejected by Apple? So everyone is making 3-in-a-rows.
