Turbo Pascal, Turbo C++, Borland C++ - not for anything I do today, but for being a big part of my gateway into programming back in the early 90's.
OS/2 - was my OS of choice until I switched to Linux full-time around 2000 or so.
Linux
Emacs
Java
Eclipse
KDE
Python
R
Postgresql
Groovy
Grails
Spring
Pidgin
ejabberd
RSSOwl
Git
OpenOffice
All things that have made my life much easier and more productive in more ways that I could probably count.
Oh, and can't forget Firefox, VLC, and XMMS. Those are essential as well.
Might as well add AWS too. For all the (fair) criticisms one could level at Amazon, AWS is an incredibly valuable resource and has been a big part of my world for the last 10 years or so.
