They have been around for 20+ years. It's called a laptop Base station / Docking station. There on a fairly wide range of buissness laptops sadly that's one of the ports that Apple does not seem to support. http://en.wikipedia.org/wiki/Docking_station
I don't think it's any sort of standard - the ones I've seen look specific to individual laptop models - and there are docks for Apple. http://hengedocks.com/
