Hi Willi,

I used vim/gvim in the past and switched to emacs. I write all my stuff
with ConTeXt and with some tweaking of the commands you can also make
mkiv run inside of emacs. also nice is to write your metapost and use
the metapost mode for it that can generate a preview inside emacs for
you. Together with auctex and reftex emacs is in my opinion the best
tool for writing TeX/LaTeX/ConTeXt documents.

So setup is:

* emacs
* auctex
* ConTeXt
* reftex
* preview-latex
* etexshow (a Browser for ConTeXt commands)
* metapost-mode+ (metapost preview)
* meta-mode (for metafont and metapost)

so far the best setup I had and where I will stay :)
