Uncertainty principle

The way the uncertainty principle is discussed implies that not being able to measure position and momentum simultaneously is some kind of mystery. Isn't it due to the fact that the act of measuring one or the other interferes with the measurement of the other? That to measure anything about a subatomic particle requires another particle or a magnetic field to impinge on the particle and produce a detectable change in state? And since how the particle's other parameter is changed can't be known, it has to be described probabilistically?
