making it almost as good as IntelliJ IDEA, albeit several orders of magnitude slower - with a significantly powerful PC, this may not be much of an issue tho'.
I use Visual Assist, which is extremely fast - normally code completion is instant, and if you type an acronym / typo, it can find what you're referring to in less than one second.
But that's not the point - I'm not debating one IDE vs. another. I'm trying to explain to him why IDEs are better than using a commandline window and notepad, and even if he prefers the latter, why the majority of developers is more productive with a good IDE.
