I also wonder what "fantastic IDE" he is referring to. I constantly hear people talk about visual studio being great but I don't believe they have ever stepped outside their world to try some of the Java IDEs like IntelliJ IDEA.
Visual Studio works fantastically for my line of work as an IDE. If I were doing some other line of work it would probably be unsuitable, but for Big Corp (tm) programming it is pretty good, much better than the Java equivalents.
