If Apple were to release a hybrid device similar to Microsoft Surface, I would rush to buy it on the release day, and I’m sure there will be millions of people doing the same as long as the device can be used with external monitors and a pointing device and run current macOS applications (even if in an emulation mode).
I would pay $1500 for such a device without much hesitation. I do a have a lot of hesitation paying current prices for Apple laptops that have only one port type and prefer older design, such as mid-2015 MacBook Pros. The concept of just a few USB-C only ports would only make sense to me in a hybrid-tablet form factor.
