In terms of running iOS apps for regular use, it makes no sense to run apps designed for handheld touch screen devices on a non-touchscreen device where the display is fixed.

For development, what’s the advantage over the current system where your app is compiled for x86? It would still run in something like the simulator app and have similar drawbacks.

I’m more excited for possibilities like FaceID, not to mention other uses for the secure enclave.

Purely speculating from a position of ignorance, but I wonder if this might be able to take over for a variety of coprocessors.)
