Ok, I agree that it can be interesting for some cases, but it is not at all what people expect when they hear "quantum computer". In addition, the comparisons with traditional methods for solving that problem show that you may as well solve the problem on normal hardware. Then the problem it solves stated as "Ising model Hamiltonian using quantum computer" is fairly uninteresting given that it is cheaper and simpler to solve the "Ising model Hamiltonian using classical hardware".
