I feel really constrained on non programmable calculators or on badly/weak programmable models, without enough freedom.

On the same way I fell constrained by having inly a few fixed variables, or losing content/history when I turn machine off/on or when auto-off automatically turns calculator off after a few minutes. All this occurs on Casio 991 or equivalents.

My first (barely) programmable device and my first scientific calculator was a Casio calculator. My first graphic calculator was a Casio (in fact, first graphic calculator on history: fx-7000G). And I own some modern Casio models, and I found them easy but very very constrained.

Even today most modern Casio calculators with complex number support can't handle most functions o complex arguments, while HP-15C did that on 1982. What is the point to support complex numbers only in a partial way? If you support them, support all available functions on them.
