You are running with sharp scissors when you play the game of using two computers and restoring from one to the other.  Chances are good that at some point you are going to hit the "oops" after you restore a client from one computer to the other.  The other half of my life outside of taxes is spent doing audit work outside of the office.  I learned years ago it was a lot easier dealing with client files to just use a single laptop with a docking station for when I am in the office.
