Watson: A leap in the medical field?

Watson, the super computer on Jeorpardy, who outsmarted the biggest brainiac that show has ever seen, might be making his way to the medical field. Working to be a Nurse, this really peaked my interest. 

Currently, IBM is working to establish the use of a Watson-esque supercomputer to help advise doctors with their work. While in theory this sounds like an excellent idea, others don't feel that way. 

There are comments from people stating "Doctors have enough knowledge." In my opinion that's ridiculous, why would a doctor deny use of such a tool to help save lives? According to the article, on average there are 200,000 deaths a year due to misdiagnosis, why not reduce that number by using this technology?
