Why HP 42S for Electrical Engineering?

In this respect, neither the 15C nor the 41 (with any hp module) can compete here, they cannot, for example, compute the determinant of a complex matrix, although they can solve a system of linear, complex equations.

I think you're correct, although I was under the impression that the Advantage Pac could do complex determinants as well...

But I must say that the best machine for EE's is the HP-41 with the 41Z module - that's the real killer app for complex support ;-) - even if it doesn't do complex determinants either but can be done with a very short Z-FOCAL program ;-O)
