ORrep:
No offense intended. Reps are indeed critical to the integration and maintenance of new, and old, technology. Interestingly, the DaVinci rep is the only rep that can routinely penetrate the gauntlet of Vendormate and the New Product Committee rules preventing uninvited reps into the OR at my "house".
However, a great salesman cannot sell a turd to anyone. If the product is sound, it will be easier to move.
