Two questions I have - which may not have answers as of now: 1. Will new app stores be able to sell iPad and Vision apps too? I.e. or just iPhone apps? Apple would obviously restrict this to iPhone apps if it can. But given apps can be cross platform/device, new app stores and their developers are going to want to sell to all devices. 2. If alternate app stores can sell to all Apple devices, will that mean as a practical matter, that the memory allocation/permissions API used for JIT on Macs, and by Apple on its other devices, will now be available to developers for all Apple ecosystem devices? Among other things, JIT API availability is required for alternate web browser, Javascript, and WebAssembly implementations. If JIT access becomes universal on iOS devices, then more serious development tools, as well as development friendly interfaces, and third party APIs, are going to be possible. Lots of barriers to serious computing on other devices will be gone. I am particularly interested in this in terms of Vision Pro + keyboard + trackpad/mouse as a complete Mac replacement for serious work. As apposed to requiring a Mac as it does today.
