You're totally mischaracterizing my response by doing exactly what you accuse me of doing. You're not hearing what I'm saying:
I've asked you to show me a list of things you can't code to do on an iPad "due to the closed nature of the OS." Instead, you've given me a list of things that aren't practical given the power of the device. That's a wholly different discussion. For example, it may not be practical or even possible to do 8K video editing on an iPhone. But not because of Apple's walled-garden approach to the OS, rather, solely because of the form factor and the power of the chip inside.
This is evidenced by the fact that you can do everything else you listed above on the Mac, on software contained within the Mac App store.
You're moving the goalposts of the discussion.
If you cant see how basic IT is not allowed on an AVP where i cant even sync my own photos over without iCloud, I can't help you. iPads have many similar restrictions. Just look at the many items rejected from the store. Basic game emulators are not allowed. Mozilla cant even put the firefox engine into an iPad in the US. Many things are not allowed past the mother-may-I and many things will not even be tried because of the mother-may-I. Not my job to educate you when you dont want to understand. We can agree to disagree.
