  A lattice model of spinless interacting electrons is used to formulate the
Landau theory of the Fermi liquid to electron glass quantum phase transition.
We demonstrate that the presence of additional random site energies does not
affect the character of the transition, once the replica symmetry breaking is
considered self-consistently at the mean-field level. Inside the glass phase,
the low temperature conductivity assumes a non-Fermi liquid ~ T^{3/2} form, in
agreement with recent experiments.
