The editor seems to work well, and since it has few moving parts,
there is little to go wrong :-}. It's pretty hard to judge based on
the simple "worksheet" in this presentation (unless I missed
something), but it looks OK to me.
The comparison would be better if the site were in some way
equivalent to what Ted cobbled up.
A couple of points in favor of the jsMath version: more ability to
use the keyboard. Even in Mathematica, selecting a particular form
plants the "template" for the form in the editing area.
In the Java version, you select the form, which gives you a floating
template, which you then have to place in the editing area (e.g., for
exponentiation). In addition, it appears only some of the components
of the equation are editable (in "X+Y", I can select and change "X"
and "Y", but not "+"?), and navigating between these "components" is
not simple ("TAB" sometimes works, but not "->"?).
I don't know whether these are limitations of the model, or of the
quick mockup Ted did.
