Question: How important are calculators?

Of those of you who use calculators in your daily lives, how many use algebraic and how many use RPN? Do you care which you use, i.e., do you choose algebraic over RPN or vice versa, or is it simply a case of what you grew up with or what an employer expects/requires? Are you in industry or education? Do you imagine that there would be a value to having Maple run on a hendheld device, one with a decent interface and good graphical display? Rich
