DISCLAIMER: this is just a reply to your questions. I'm not at all
trying to convince anyone to use it or even less going into a flame war
(that I don't grokk since each one has it's own preferences). It's just
that I use it and now anything else seems... just not enough.
Emacs is just the platform, forget about it.
Org-mode -is simply put- a great tool to write. Just opening the org-mode
box you have:
+ an efficient outliner (expand, collapse, rearrange, focus, etc.).
+ simple but powerful structural and semantic markup.
+ versatile comments by line, region or branch, etc.
+ powerful editing abilities (automagic expansions, corrections,
linking, transposing, etc.)
+ great latex (and other formats) export: solid, documented and clear.
All this contributes to a super sleek writing flow. The tool never get's
in your way at all, but silently supports you. And can keep doing it
while you grow since it's highly customizable.
Also, the "terminal" appearance is only if you use it through a
terminal: I have it in a desktop window and use my selected fonts and
colors so there is absolutely no legacy look here. And I'm no programmer
(I studied Biology), and there are other writers out there that found it
useful. :)
Again, just to clarify. If it doesn't help, just leave it. :D
