Software developer for a living, I tend to spend way too much time on it after work as well...
"Born and bred" Microsoft adept, I'm currently rather in(to) the Delphi corner of the world. This hasn't prevented standards-based languages like XML, XSL, (X)HTML, CSS and Javascript to open my eyes to open source environments, which have been alluring ever since.
Perhaps Delphi Prism and Mono will finally provide a way to bridge both worlds...
