Just ordered a DM42

[Dave Britten]

I've been using my DM42 for about a year and a half now. While there's certainly room for some improvement in the keyboard feel, the software and internals are top notch. Using RPN (particularly programming) is quite different from RPL - some things are easier, some are harder - so being good with both gives you a lot of flexibility.

Here's a non-exhaustive list of programs I keep on mine, in case you want ideas of what to do with it:

- Stack save/restore routines
- Probability programs (binomial distribution, negative binomial, Poisson, hypergeometric, etc.)
- Floor, ceiling, GCD, LCM
- Some matrix routines: column/row/whole matrix sums, min/max, sort
- Unit conversions (One that I wrote; easier to add new units than the traditional unit conversion programs that were floating around prior)
- Triangle solver
- Flag browser
- TVM/amortization package
- Many small solver programs for various equations
