I'm suspicious that I won't find it useful. Pencils and paper are awfully nice. I bet that even a trained user of this software can't write an equation faster than I can.
Sometimes it is nice to be able to typeset equations, or feed them into Matlab or Mathematica, and I guess this might help with that. But I don't own Matlab or Mathematica anymore.
And, yes, the paper requires you to know that m is a mass with units of kilograms and q is a charge with units of coulombs, and that the m in one equation is the same as the m in another. But if you can't keep track of that yourself I'm not sure why you're bothering to write down equations.
