Have you tried TheCalcMan?

Its good.
You need only the keyboard to operate.

XCalc shrinks down to a tiny stay on top window and is always handy.

Easy but smart calculator:

Calcute

I use pmaCalc a lot. It is freeware, very handy, have almost all necessary functions and converters and it is very light.

XCalc is what I use when I need a calculator.

For repetitive stuff like adding a column of numbers, I use an excel spreadsheet.

Must see this:

I have tried many, but ESBCalc is the best I think > http://www.esbconsult.com/esbcalc/esbcalc.htm > fast, free, and easy..

speedcrunch

powerful and easy at the same time!

XCalc

moffsoft.com - makes a tape. I use it a lot.

I haven't actually used it, but Sage is supposed to be a good replacement for Maple, or other Engineering "calculators"

Microsoft PowerToy Calc is an excellent free one. It is supposed to only work on XP, though if you install on XP and copy the installed program folder over it will work on vista.

A good one is: SpeedCrunch

It would be nice if someone looked at the suggestions so far and made the article...
EDIT: SpeedCrunch has a portable version around. And is in linux, windows and mac...

The most complete free calculator I have found is GraphCalc
http://www.graphcalc.com/

It is older (last update 2003) but has a very nice and clean interface. It also has all the functions a basic and advanced user ever could want such as:
1)A huge database of conversion factor and physical constants
2)2D graphing in rectangular, polar and parametric coords
3)3D graphing with full panning and rotation <--VERY USEFUL!
4)Advanced modes and functions (stat, trig, equation solver ect...)
5)The ability to export graphs and output for use elsewere.
6)The option to work in any number system from base 2 (binary) to base 36.

All this comes in a very modest size w/ minimal system bog down!

I use Calc 98

If you are looking for an RPN calculator, try http://www.tordivel.no/xcalc/. It's tiny, starts super fast, and has keyboard shortcuts for almost anything.

I was an accountant, and accountants use ADDING MACHINES. These are slightly different than calculators, they work something like a cash register. Most calculators do not use adding machine logic. I found this program that lets you run a virtual tape, and acts like a real adding machine. This is not designed for science or graphing, and if you dont actually understand the difference between adding machines and calculators, then you probably dont need it. If you do any accounting/bookkeeping work, then this is for you.

mark's adding machine
http://mwganson.freeyellow.com/MAM/
Mark's Adding Machine (MAM) is an adding machine / calculator for Windows 95/98/ME/NT 4.0 or later. It features support for multi-column printing of tape at user-selectable font sizes, support for text-to-speech engine for reading back of tape contents, spreadsheet and wordprocessor program integration via Windows clipboard, user-definable macros to automate repetitive tasks, separate memory LED, mouseover status bar quick help, and, best of all, it's FREE!

Don't know if this is still valid (as its not stand alone), but a FireFox browser plug-in, 'Calculator'.

It opens up under a new tab and features a tape function, trigonomic functions, and conversions.

Moffsoft FreeCalc is an excellent Free Calculator Program.

Visit http://www.moffsoft.com/freecalc.htm for program details.

Very simple and easy to use. Visual tape is excellent for verifying entries. I use it all the time. Set it up in your task bar for easy access.

I like this guy. "Microsoft Calculator Plus" It's nothing too advanced (so Engineers look elsewhere), but it is a step up from the standard xp system calculator. It includes some convertors as well.

If your looking for a practical and easy to use calculator that you don't need a physics degree to understand its use, try power calculator by microsoft.

I found a nice calculator named HEXelon. I didn't look for all of his features but I found traits I was looking for. It has nice interface and design. He has a really big display. He has a lot of functions. It seems that most of functions are hidden but you can include them in interface if you like. You can also define yours functions and variables. On official site there is a collection of functions which are made by users so you can include them in calculator.

It's free for personal and commercial use. It works on Vista.
Official web site is: http://www.hexelon.com/kalkulator/index_en.php

Here is an excellent simple calc...

http://www.moffsoft.com/freecalc.htm I like this for its simplicity and very accessible visibility of what you are doing

For those who find RPN (Reverse Polish Notation) easiest, X-Calc is very good - http://www.tordivel.no/xcalc/

I have for the last couple of years been using the following two free calculators (XP Home) on a daily basis:

http://www.calculator.org/download.html
with the standard functions normally found in a scientific pocket calculator, and

http://www.atomixbuttons.com/textcalc/
which is a combination of an expression calculator and a text editor.

How about speq?
http://www.speqmath.com/index.php?id=1
Tiny, portable, and has myriad features.

GraphCalc ( http://www.graphcalc.com/ ) is also competent, and can do 3D graphs, but has not been updated for five years.
