I don't think there are a great number of surgeons for whom not having a stapler and/or vessel sealer was a deal breaker. If it was that important to them, just use manual devices through the accessory port. Secondly, general surgeons tend to have better laparoscopic skills and a lot of them don't see a benefit to robotics on more than a few surgeries. That will probably change over time, but he days of rapid adoption and growth are long gone.
