I would say that OSX is preferred by any power user who needs/wants access to a "desktop"-style UI, a complete filesystem experience, layered windows, etc. The bizarre opaque filesystem on iOS drives me crazy, and is one of the biggest reasons I've had trouble committing to an iPhone.

I don't know of many people working in an office environment, much less as a developer, who would be satisfied with an iPad Pro as a daily driver when it comes to getting the amount of work you can get done on something like a Macbook Air.

Perhaps I just don't understand iOS well enough. I'd love to see a video of someone actually working and multitasking effectively on an iPad at the speed that is possible on a Macbook. Most of the videos that Apple releases show work that is limited to video capture, editing and illustration.
