Honestly a dex competitor would really help keep me in the Apple ecosystem.
With the power of M-chips, this would cannabalize MacBooks via iPad Air / Pro. They are sitting on a golden cash flow and not willing to revolutionize computing again (as the iPhone did).
Just as a N=1, I would rather pay a recurring fee in the Disney-Netflix range to Apple to get more liberty in usage from my machines. But I think they don’t dare to go those routes, because they need the broad market base and cannot extract the current cash flow from a smaller base, while setting expectations that the Googles, Samsungs can copy.
Industry leaders dilemma. Apple currently settles on market differentiation via physical products.
File a Feedback request to make the “external monitor support” available on iPhone and iOS. This is essentially the equivalent of Dex for iOS.
The more people that file, the more likely it is to happen.
