My main reason for preferring paper over keyboard is that I like to draw example graphs of everything. These don't need to be exact just give a visual idea of how a function acts.

I also heavily annotate equations (color code, add description, etc)

How do you get around this?

The flexibility you get with pen and paper, e.g. draw arrows between arbitrary words / equations, you can't really beat.

But for the specific use-cases you mentioned:

- Org-mode allows you to integrate code into the document, hence to draw a function you could easily write a small snippet of code outputting a plot, which will be embedded in the document.

- I actually do this sometimes too! For the color-coding, Org-mode allows you to embedd arbitrary LaTeX such as "\textcolor{red}{\alpha}". I've set up a Yasnippet which lets me type "color + [TAB]" and expands to "\textcolor{}{}" with my cursor inside the curly brackets. I type "red" and hit TAB again, and then type whatever I want to be coded in red. For descriptions, I'm unsure why you couldn't as easily do this in a document. In my documents I usually have a larger body of text deriving/explaining the equation, and then I simply put the equation into a definition-block for further reference. Then I know that I can jump to its definition, and I'll find a more thorough explanation of it.
