One major advantage of RAW, in addition to the previously mentioned
ones,
is that you can easily edit the RAW image, non-destructively.

You can edit anything non-destructively. Keep trying.

except that jpeg is already destructive.

you can edit non-destructively from that point on, but you can't undo
what was done to make the jpeg.

Interesting you said that - I stumbled upon a function of Elements that
sorta converted any JPG into a RAW file and allowed you to edit it the
same as any RAW image. Do you know what I mean?

Sure you can convert an 8 bit Jpeg into a 16 or 32bit file in PS if you
want. Of course the data lost when saving from a 12-14 bit sensor into an 8
bit Jpeg is ***NOT*** recovered!
Editing and saving as a 16 bit PSD or TIF at least means you don't lose
progressively more at each edit/save, but is no substitute for starting with
a decent file in the first place!
