I agree. The difference between an IDE and a text editor is absolutely not that an IDE has more advanced editing capabilities (e.g., code completion). In fact, it's quite the opposite, in that most programmers' text editors provide far more sophisticated editing capabilities than a typical IDE. What sets the IDE apart is right in the name: integrated development environment. That is, everything you need for development all rolled up into a single integrated environment (hopefully, this is obvious). So, an IDE ought to provide not just editing capabilities, but facilities for managing, configuring, building, running, testing, debugging, etc.
