Ah, ok.

There probably have been quite a few improvements since "long ago",
mostly in the performance area, but it also can now deal with PDFLaTeX
and make judicious use of dvipng if available (mostly a performance
thing).  We also made a number of changes to AUCTeX's filling code
that tend to keep linebreaks out of preview material: this leads to
considerable improvements in the resulting buffer display in
particular with inline math.

Apart from that, I don't think the user interface changed much,
though.  Still, trying it does not require any commitment (like
working with LyX would): you can use it on any document or parts
without any net change on the document itself.

Personally, I don't use those shorthands but the equation* environment

Perhaps we should have the environment insertion commands also accept
matched stuff like , \left...\right, or revert to C-c C-e-like
behavior for TeX-insert-macro on such matched constructs.
