I don’t think this is true largely because an experienced text editor user will generally have access to most of the same capabilities in a different form. Where there are differences, the win sometimes goes to the ide, and sometimes to the text editor, but generally people adapt their tools to themselves, and themselves to the tools, and in the end it shakes out to be about the same level of productivity.

I’m not convinced that people can easily switch though. I’ve met people who never really get the hang of working efficiently in the “Unix is the IDE” style of using text editors, and I can say from personal experience that I’m just never going to be particularly good at IDEs. I suspect that each tool simply appeals to a different personality type- and that’s okay as long as our projects don’t lock us in to something and we let people have the flexibility to use the tool that works for them.
