If electronics, mainly cpu's and memory capacity, had stood still without the evolution of electronics then I would say you have a good point, however, 40 years of evolution means that hp calculators are somewhat dated now.

Darren, thank you for your reply.

It's possible that we may be mixing up hardware and software. The recent mix of 15C calculators (e.g., 15C CE, DM15L, PX-15C) are not running on 40 year old hardware (the 15C CE runs programs up to 200 times faster than the original 15C) and have benefited from the the evolution of electronics.

Remarkably, on the software side, the feature that all functions accept complex arguments is, 40 years later, still a distinctive quality of the 15C (and the 42S) compared to many or most newer calculator models.

Where I agree the design shows its age is that the program display only shows numeric key locations rather than alphanumeric function names (though the PX-15C provides both).
