Still, linear algebra is the basis of a lot of more advanced mathematics. But I agree, it can be dull.

Well, I am reviewing it for a Quantum Mechanics and Computing Course. I may be raving about how useful it is once I see its applications.

In quantum mechanics, one is usually interested in infinite dimensional spaces, so really that is functional analysis. But, in quantum information theory people usually consider a finite number of states, usually 2. Here you really do use linear algebra. And amazingly, there are still open question in linear algebra that come from quantum information theory!
