Of course, I could have folded a slew of other things that weren't
folded there. Emacs can also display equations and figures in-line if
set up properly. I've had it set up, broken it, and realized that I
really didn't care to use it much.

The best way to see what auc-tex (you don't use emacs on latex
without using auc-tex) can do is to look through the manual, gleaning
the parts of interest.

Aquamacs. Mostly because they have been working on getting it to
behave more like a Mac App, at least with respect to some of the key
bindings. I use it in x-windows because early on there were some
stability issues I found with Carbon Emacs. I think these are
resolved, but I've never bothered to switch. Plus, I've gotten quite
used to the standard key-bindings.

If Emacs/auc-tex had a menu item for everything it could do, it would
look like MSWord, with menus from hell. It does it's best work with
key-bindings and meta-commands (metakey-x type the command, or best
guess, etc, tab to complete). Emacs/auc-tex is the kind of system
that you never remember all that it can do. You can read the manual
multiple times and continue to find new stuff. Even then, I forgot
about using folding altogether (doesn't bother me that much if stuff
isn't folded).

Yup. It has had it for years with DVI files. pdfsync allows it to
work with PDF, of course. I personally use TeXniscope, but it can be
done with TeXShop or iTeXMac (I have it set so that I can go from
emacs to display in either depending on the key-binding, and both go
back to emacs!). Note that the synchronization that TeXShop has (not
using pdfsync, but using search), seems to be better IMHO. However,
it's good enough most of the time.

Here's the cool thing. It's only text! You can switch between editors
when ever you feel like it. I use TeXShop a lot, as well as iTeXMac.
It really depends on what I'm looking for at the moment, and which
tool seems the best at the time. It's not unusual for me to switch in
the middle of editing to a different editor, although I think I'm
probably pretty unique that way. I think I switch as a way to get
over "writer's block". I get a change of scenery. ;)
