I’m afraid the operating system on a Mac Pro or Laptop is going to become this iPad like interface. Then everything will exist in the “cloud” and we will be back to this mainframe like super system. We will have no control over the devices we buy. Everything will then become subscription based and we will be paying for these services like a cable bill and be beholden to these people for basic services the way we are beholden to the electric or phone company.
But someone else will figure out a better way. And Apple will not longer be what we grew up with.
I do like the idea of a Minority Report touchscreen like editing interface though. That could be cool.
