While I do agree that development, build, and testing shouldn’t rely on a single IDE/toolset, I have to admit that I really do enjoy the explorative properties of many of the current IDEs for Java, C++, and C#. When I need to dig through foreign code I always find it a lot easier to do it using a IDE that has good jump and search capabilities like Eclipse.
