I tend to disagree here (and not only here :-). Newton's laws are
invariant under Galilei transformations (e.g., x' = x + v*t, with
v=const), whereas Maxwell's equations are not. They are, however,
invariant under Lorentz transformations, and I think that's what Einstein
lead to applying them to mechanical problems as well, in order to explain
the Michelson-Morley experiments. The rest is history...
