Hrm? On a conceptual level, is there more to QM than the Uncertainty Principle and Wave-Particle Duality? DWLM mentions the competing interpretations, but choosing an interpretation is not strictly necessary to understand QM predictions.
For clarity, I consider the double-slit experimental results to be an expression of wave-particle duality.
I will admit that DWLM does a poor job of preventing billiard-ball QM theory ("Of course you can't tell momentum and velocity at the same time. The only way to check is to hit the particle with a proton, and that's going to change the results.").
That's a wrong understanding, but a less wrong understanding than "It's classical physics all the way down."
A deeper, more natural way to express both is "wavefunction reality," which also incorporates some of the more exotic effects that come from using complex numbers. (The Uncertainty Principle also should be called the "uncertainty consequence," since it's a simple derivation from how the position and momentum operators work on wavefunctions.)
(I haven't read DWLM, so I can't comment on its quality.)
