Germany and Prague

In about 5 weeks I will be going back to Europe, this time visiting Germany and Prague.
I am flying into Munich, flying up to Berlin, taking the train down to Prague and then another train back over to Munich. I got a flight on Lufthansa from Munich to Berlin for about half the cost of a train ticket, and since the train is over 6 hours and the flight is just over 1 hour, I am saving time as well.
