Working on iPad is more focus

Using iPad is more focus than using macOS, thanks to the nature of app-based environment vs. window-based environment.

Moreover, Mac has so many background processes that are running and thus sometimes make the main application not fast response enough, even with an i7 core. 

For iPad, especially iPad Pro, the iOS is so fine-tuned that all the processor power is dedicated to the current active app. App never response slow. Never.

So for works that iPad can’t do, I need a MacBook. But for work that both Mac and iPad can do, iPad is clearer the winner.
