Future MacBook Pro devices could be fully virtual as Apple is investigating creating them in AR, and also assessing when we need a screen break.
In the future, we may never again have to wait for UPS to deliver a Mac, we may virtually conjure one up in front of us. Put on your Apple Glass, or other Apple AR device, and have the MacBook Pro of your dreams appear in front of you.
Apple already uses AR to show us what a Mac might look like on our desks, but a newly-revealed patent application goes much further. There still has to be an actual MacBook Pro somewhere, but the virtual one in front of you will respond to your key presses, and display what the real machine would.
