I guess the āawkwardnessā of the experience depends a lot. Even if Iām a heavy Mac user, Iām used to the phone paradigm, where interaction is much more direct, and I find it much easier and enjoyable for everyday and creative tasks. Using an iPad is much more natural than a traditional PC to me.
Regarding the second paragraph: I think itās much, much harder than it sounds. The iPad would need to run two OS, switch on the fly whenever you connect some accessory, reboot, and suddenly you end up loosing the context of what you were doing before. And now the touchscreen canāt be touched. What happens if you disconnect the MK by mistake, for example? There are many compromises made to end up with a bad experience, awkwardly switching between OS that look completely different on the same device, which is not designed for macOS in terms of battery, size, thermals, trackpad size, etc. I think itās an idea that sounds good in theory but wouldnāt work in practice.
