The way you can tell an idea's time has come is that it starts showing up everywhere. ;-)

Sorry, but wiode isn't an "IDE" to me. What's "I"ntegrated? Where's the "D"evelopment "E"environment? While I do appreciate and like the push to new technologies, let's keep the terminology straight....

Coloring some keywords might make things look pretty, but it surely doesn't make it all by itself an IDE or even a good text editor. Line numbering isn't a 'feature', that's a basic necessity. If these things are taught as 'features', what else is a 'feature' then? The ability to save the text without errors? Let's raise the bar here, please.

For me, Eclipse or VisualStudio is an IDE. Aptana (now Appcelerator Studio) is also more than just an editor. TextMate, VIM, Notepad++, UltraEdit and the like are not IDEs. They are (mostly dumb) text editors.

Personally I draw the line at whether there's contextual code-completion provided via instant introspection or background compilation.
