HP35s any good for EE?

From a pure practical perspective, IMHO, the sweet point for everyday EE use is between a "top-end" RPN machine (say, the 42S) and a "low-end" RPL one (say a 28S or 48S/SX).

I don't have such a long history using HP's for electrical engineering; just passed from a Casio FX-4200p to a 48G.

It transparently works with complex numbers and matrices and, as a premium, it also works with units, a capability I really miss in RPN calculators. The 48, being it one of the first incarnations of the RPL style, lacks some later "features" I think are not necessary for an everyday calculator (say: big CAS, too many "menu applications"*, equation libraries,...). It does also have the classic HP keys on its classical orange/blue colour theme.

Of course it is not perfect, I miss better probability distribution support & eigenvalues (48G does this last).

I totally agree. Well, I'd recommend a 48G+ that will have the "black LCD" that is a dramatic improvement over 48S and 48G blue ones.

For an Electrical Engineer the use of complex numbers is crucial, and you will need a calculator that can work with them as they were reals. The 48 series does that; I'm not so sure about the 35.

But you can still use the "old way" to set flags or use the solver...
