|Ideas for new HP Business Calculators|
Message #1 Posted by Peter A. Gebhardt on 25 Sept 2006, 6:01 a.m.
During waiting that my trusty HP 17BII+ finished his MIRR & FMRR (Modified IRR & Financial Management Rate of Return) calculations on a midsize cash-flow problem, I started to think, how the HP business calculator of the future should look like.
Here are some ideas (albeit unstructured) - I kindly ask the readers who depend on business calcs in their daily work too, to comment & add ideas & features!
- Formfactor of 17BII+ or 19BII
- power-on time with one set of batteries should be retained (hard to acomplish - I know - giving the feature list following below)
Listed features are in addition to existing HP17BII+ features:
- It should be much faster. Goal: Surpass the speed of a TI BAII Professional Plus when doing (as an example) MIRR
- It should include IRR, MIRR & FMRR routines in one menu
- It should allow for LIST editing
- More internal memory
- Additional programming possibilities beside the SOLVER - BUT Keep the Solver !!!
- It should allow for data storage/exchange via SD card
- It should have USB or (real) IRda
- It should provide TRIG functions
- It should provide UTPN etc. functions
- Backup Battery instead of condensator (to support secure battery exchange)
