Main thing is that combination of Arduino and MK802 removes the need for the cable as seen in this case: http://youtu.be/jf-cEB3U2UQ#t=11m28s And yes, by shown example all the computing power for machine vision etc. is now on board. Not to mention node.js javascript and firmata. Your observation about new computing power on board which becomes available is right. Lame? ... I'm sorry to hear that.
