A lot of people are focusing on the user experience in their commentary here, which I totally get, and I would argue is the most important part of this initiative. I personally have a lot of open questions about how a user interface will work across different paradigms (touch and cursor). The first Marzipan apps (News, Stocks, and HomeKit) have lots of weird corner cases and sharp edges. Specifically, some of the "elder statesmen" of Apple commentariat see Marzipan as a threat to the old Mac indie app ecosystem. I get that, and I think that there are definitely some aspects of the old paradigm that are at risk (ie, AppleScript integration, etc). However, I'm giving Apple the benefit of the doubt here. 1) Apple is unmatched in their ability to design user interfaces. It is entirely possible that they will come up with a solution for cross-paradigm interface that works, or come up with a system to "translate" an interface for multiple target paradigms. 2) Apple has a history of successfully pulling off large transitions like this. In fact, they might be the only company that has done this successfully multiple times. (That is, architecture change and UI framework migration). On top of that, I think all the doubt and suspicion has to be weighed against the following upsides: 1) The upside for the Mac is enormous. The sheer amount of software that could immediately become available on the desktop would probably be the worlds biggest inflow of software to any operating system, ever. And, it is, for the most part, good software. 2) This is mostly a move on behalf of developers. I get the "but no one asked" responses, but the developer story here is probably one of the major reasons Apple undertook the work (that and ARM). 3) This is Apple's answer to Electron for the Mac. It will undoubtedly be better in user experience, performance, and resource usage. (We will have to wait and see whether it is successful, though).
