Great, except we paid for all features, not everything but one.
Great. And they should ensure it works given they demoed it.
So?
I can't imagine any iPad running iPadOS 15 would be limited to two apps since they can already run 3 apps at once.
Redundant to point 1. Still not sufficient. It would be better to not launch the feature than to arbitrarily fragment the ecosystem by claiming one chip can do it while another that can do it, won't. Apple messed up. They shouldn't have launched this feature with iPadOS 16, or they should have launched the last generation of iPads with M1.
I am going to stop you right there. I expect every feature released for at least 3 years, with most features without clear hardware limitations (which the M1 is not one) for five.
They did. That's all that matters.
I purchased it with the expectation that all features for the next 3-5 years would be on the iPad
Yet Apple sells iPads on this promise.
They are obligated to provide every feature we paid for. They charged more upfront with the promise of future OS updates. Are they issuing me refunds or account credits because they failed to deliver all features to the hardware they sold? No? Then deliver on promises.
