What do you like most about the HP 15c?
The HP-15C was my go to calculator at my first post-college job, and for many years after. RPN was already my go-to calculation mode, and the rich functionality, gorgeous display, fantastic keyboard, and incredible battery life of the 15C made it a joy to use and an extremely useful part of my toolkit.
What battery does the HP 15c Limited Edition use?
A side by side comparison with my 30 year old HP 15C and the new HP 15C Limited Edition confirms that HP has done well bringing back this vintage calculator. The case seems to be based on the current 12C platform, that uses dual CR2032 batteries.
Is a 15C calculator worth it on a smartphone?
Sure, there are larger, more powerful calculators, and there’s probably a 15C emulator for your smartphone that will cost a whole lot less, but the tactile feedback of the keyboard is worth it, at least for me when I take into account the very fond memories it evokes with every use.
