Looking for the difference between operations of a NON M model versus an M model. Have a couple friends interested in the 6000 series rigs after hearing and using mine, however they have questions regarding what can't be done easily or at all with an M model versus what can be done on a Non M since it is PC controlled. For the sake of this question Assume NO PC on the M model would be used it would just be a standalone operations verses a NON M model used with PC . What difference in operations cant be done between the two setups. This includes using 3rd party software applications as well. Is there really any difference other than having the front panel touch screen display or our there options that the PC controlled setup offers that the M model can't do on it's own.
