I am going to want to run three docking stations and three computers.

I currently have a Latitude 16410 and a docking station for it.

I want to have two computers for business and one for non-work related things.  I don't want work and non-work to mix.

My goal is for any of the three computers to work on all three of the docking stations.

I am willing to give up the docking station I am using for another one if I have to in order to have the greatest amount of compatibility possible.

Is there a quick easy way to figure out what the greatest compatibility combination I can have doing this.

I don't want the computers to look identical as I want to quickly and easily know which computer is which without turning them on.
