HP-39gii, IMHO, is one of the best calculators for engineers I have ever bought. Quite good design, the high-quality keypad, speed and reliable algorithms. Unfortunately, unpredictability in operation, the unfinished solutions in power supply and in data security from loss don't allow to use all its potential.
Still it is necessary to increase RAM, to add saving of pictures, to eliminate flicker of the display with ~20Hz. At least. If to add "complex mode", it will be the super calculator. I don't understand why HP wants to do nothing with that.
