Ok so Steve Job's outlook for computing was to envision devices iPhone iPad and now iPad Pro and Macs essentially as cars or autmobiles. Stay with me here just like cars and trucks some are suited for particular tasks. A garbage truck or a race car. Fine. Now that we have such a variety of use as in the iPad Pro it is kind of silly to be running the same OS across these differnt devices which like cars and trucks are suited for differenet uses. How many more OS releases will be stuck with the same icon arrangment or no file system or USB drive support. I can see how an iPhone would not need such enhancements. But an iPad Pro. This whole Replace your PC may backfire on Apple if they don't wake up. We need basic functionality they are intentionally keeping from us.
