Display graphics in Vim? A REPL within Vim? This is precisely the main advantage of Emacs over Vim: Connecting to external processes and doing more than just text editing.

(Don't get me wrong. I am not saying that Vim is bad. But this kind of thing just does not fit its mission statement)

I have access to CL REPL inside vim without any problem. Slimv work pretty fine for that, even with Clojure...

True, REPLs are possible in Vim. Terminals are possible, too. It's not that anything is impossible (it's software, right? So anything is possible), but how easy it is.

Emacs was built for that. Vim was not. Which by the way does not say anything good or bad about either of them. But I would dare say that Vim is most commonly used alongside a terminal, whereas Emacs users tend to run terminals inside Emacs. Hence your normal workflow would be to run iPython alongside Vim or within Emacs.

Indeed, the Emacs buffer is amazing, it supports not only text, but graphics, which means anything, perhaps even 3D someday!

3D text editing? Why?

Because we can?

OK, conceded!

Good point, and a reminder that not everything needs to be ported to Vim (just because it can be).

Using Vim Script? That doesn't sound like fun.

Maybe Python? I understand Emacs is more than an editor, and maybe better suited to this type of integration.

I've never tried, but VIM already got nice looking IPython binding (https://github.com/ivanov/vim-ipython). I think it doesn't support notebook editing though.
