I don't really see how this is a poor decision on apples part. For windows sure, right clicking abounds, though I'd argue that right there is the crux of the problem in general. The over reliance on right clicking in user interfaces I think isn't too far off from "magic track pad pawing motions like triple swipe etc...". But that last bits mostly my opinion on the matter.
> Avoiding right mouse clicks in the name of simplicity
Simplicity has nothing to do with form, that is function.
> Designing thin laptops instead of durable laptops.
Thin/light laptops has nothing to do with form, that is function (who wants to carry around a brick?). And what is more durable than a MBP anyways?
> Restricting installation on iOS to just the App Store.
Security and safe experiences has nothing to do with form, that is function.
"Form" would be fashion, and Apple definitely has plenty of that, but all the points you listed don't focus on that.
Apple introduced multi touch to solve problems just like that.
