We've been using a beta version on the Mac for a while now, and the
program, well, is still in beta stages.

The earlier comments about RAM-hunger are definitely true.  Especially
if you like symbolic math.  Our 2Mb MacII shuts right down when we
try to invert a 4x4 matrix.  We hope to get some more RAM to fix the
problem.

Also, Mathematica is not as smart as we were hoping.  For example,
to invert a rotation matrix by hand, one usually transposes and
then takes the complex conjugate...But Mathematica fails to
recognize things like sin^2 + cos^2 = 1 and things like that, and
doesn't do the inversion properly unless you tell it that.

For direct numerical evaluation, though, Mathmatica is fast.

Does anyone know if the "real" version is shipping?
