Very useful pro calculator.
- No graph function, use computers for what they are good at and calculators to what they are good at, ie a flexible tool
- Good formula manipulation (with the solve)
- Build quality, buttons and chassis seem to be able to hold many years
- Good management of different number bases and different representations of such complex numbers which are based on viewing mode istf. converting single values
- RPN Again, it's soooo good!
- Stingy description of the progam and subroutines, a letter: AZ. It would have been good if you could write a little explanatory text, or give real names to their functions. The case should have had a place for a memo.
- Matrix Computations missing, on the other hand maybe Octave / Matlab are better tools for this stuff
- No back-up function, a USB port or RS had been good
On the whole a cruel counter that I will have for many years unless HP comes with a sequel to the 41: th
A very formidable counter. Got it as a replacement for my Texas Instruments TI 30X IIB that served me for many years. Wanted a programmable and I thought it was about time that my Texas received serve as a living counter.
Very easy to change batteries in that they do not need to screw up the whole counter with the former. Just replace one battery at a time and it does not loose memory. Followed with an artificial leather case, quick start guide and a user's manual on CD.
