What really isn't mentioned here in the threads, and the thing that really caught my eye, was the inspections. The notations of where potential errors were in the code. This is amazing, and would make code reviews so much easier.
This struck me as one of the most interesting features too - especially if it keeps track of new static analysis issues introduced/fixed in code - currently I use TeamCity and it's got integration with inspections too but it would be really interesting to see a good UI for exploring this data as it changes across commits - like Sonar
