If your comparing the RTI to the 2.0 versions there are several differences, but to give you the general idea, the Nevo software is more flexible and accomodating in graphical placement, importing, etc. The RTI software is more powerful from a technical level. There are many, many different layers of features that can be utilized, and the technology is different since you are storing commands on a processor. Its like a mix between CCP, Nevo and Pronto, but very polished.
