I know plenty of people that only use their ipad pro or macbook and refuse to carry buy and carry two devices, or are like me and won't buy any apple computing device until it satisfies my needs. It's not a given that everyone out there is just going to buy both devices or can even afford that. You could be spot on for the reasons this doesn't exist right now, but Apple is for sure missing out on new sales by not offering something like this. Hard to tell how the numbers would actually play out unless they actually released something.

I wish that Apple would release an apple pencil compatible display. Wonder what that would do to Wacom's business.
