Tim, in rereading your response now I'm a bit confused.  Do you mean I should get a Multimaus handheld throttle or an entire system (throttle plus Roco 10764)?  I completely agree that the Multimaus has a much more elegant interface-- when I operate trains I am continually consulting the manuals which drives me absolutely crazy-- as you said, so much for a good user experience!  Touchcab was going to be my solution to this.
