Quantum computers have a lot more utility than factoring integers. How about simulating molecules, or solving classically hard optimization problems?

Which optimization problems are you thinking of?

Graph coloring, SAT problems, eigenvalue minimization. Almost any binary problem where you can write down a cost function.

Again, you're thinking of an NTM not a quantum computer. There are some number theoretic problems, only:

Are you thinking of the adiabatic QC approach (i.e., the dwave machine)? I think they still haven't been able to show that it's faster than a classical approach for any problem.
