I'm about to request arch teams mark x48 stable, an awesome hp48 calculator emulator. If you own an hp48 calculator you can use the utilities accompanying the package to dump the firmware from it and use x48 for any purpose, otherwise you will have to use the firmware image provided by hp that is only available for non-commerical use. If you've never had the opportunity to use an hp48, you should definitely give it a try.

There's a screenshot of x48 in action here.
