What calculator do you use ?
Lightages:
I have an HP35S and I am impressed with it. it does everything except graphing and is in the traditional design that HP was known for. Well it doesn't have the double molded keys but the feel and colours are very ergonomic.
There is an open source project based on the HP20/30 that is also very interesting.
This person is selling a pre-modified product at what I think is a reasonable price for his time:
http://commerce.hpcalc.org/34s.php
There are also links to the project.
For the most part I use the emulators for HP calcs on my Samsung Galaxy SII, but still like the physical feel of real HP calcs.

I found an open source emulator that works under linux of a HP-15C. Installed is yesterday on my pc instead of the standard calculator. I am on my Ipad now so i cannot link it but if you search for HP-15C emulator you find it. It looks just like the real on.

I have an HP 35s.
Bought it 3 years ago. I was quite new to RPN back then but quickly learnt it and fell in love with it.
It replaced my old Casio FX83MS. Now, whenever I get the old Casio out I forget how to use it.
My only major complaint about the 35s is the display, it isn't very readable in the dark. I wonder how easy it would be to bodge in a backlight.

HP42S, along with an ancient Casio FX602P. most commonly though are the real simple ones in the cellphone, or the built in scientific one in Debian gCalctool. More often then not a pen and paper is sufficient.

My HP-15C limitted edition just arrived. I love it. The 35s can do more, but the 15C does all functions I use too, but is a bit easier to use. Also a very clear display.
