Usability is everything

In the video below, somebody combined 3 ideas

• Use the accelerometer in your Mac to detect a tap
• Use a tap to switch Spaces (Apple's marketing speak for "virtual desktops")
  
• Run Windows in VMware Fusion, on one Space, in full screen mode

And came up with a nice solution to the usability problem of working with several computers.

Abstract objects, when manipulated using tools available to us in the real world, immediately become much more concrete.
