Must See Tool Tip

All the discussion of calculator apps encouraged me to highlight my favorite.

I'm a great fan of RPN calculators and especially programmable ones. A quick calculator program can often save the effort of an actual computer program or (spit) a spreadsheet.

Educalc has written a complete emulator for the HP 35s, Hewlett-Packard's newest programmable RPN/ALG calculator. It can be downloaded here...

It's free so it's a great way to introduce yourself to RPN if you aren't yet familiar and, since it's programmable just like the real calculator (which I also own), you can learn programming too.

I use it for all my onscreen computation despite the fact that the real thing sits in a desk drawer right by my left hand.
