Personally I think Vim has been an IDE for at least 10-15 years now. You could argue for a long time about the exact definitions of "IDE" and "editor", but Vim can do compile-cycle, completion, finding identifiers, file browsing, spelling checking, terminal window, debugger, scripting, and a bunch of other stuff out of the box, without plugins. It certainly does these things different than your average IDE. Again, you could argue for a long time about what is or isn't an "IDE", but merely "editor" really does injustice to some of the more advanced features in Vim because it can do so much more than just "edit text", and "IDE" certainly seems a lot better of a fit than "editor".
