How and why do you use your HP calc?

[Jim Horn]

Electrical engineer. Use my 50g at work: pressing a single key is still faster than typing "sin", especially for more complex functions. And at work I don't have Mathematica as I do at home.

Home: Use my WP 34S. Don't have to open another window and create a notebook, etc. just to bang out some values. If I need to do something many times, its programability handles smaller problems well. Mathematica handles the heavy lifting. And Excel/Open Office Calc spreadsheets are interchangeable with anyone else.

What gets calculated? Mostly EE stuff: Circuit component values and conditions, radio frequency communications simulations but also hobbies such as amateur radio, astronomy, aviation. Plus the inevitable chores of taxes, budgeting, etc. With a brain tuned for RPN, these are my best tools.
