Just to clear things a bit: I "use Windows" not as often as Linux. I am forced to, because some of my hardware is sadly dependent on Windows, and I have to use Visual C++ for my thesis project.

Thanks, Visual Perl looks nice. I'd consider using it for the times that I am in Windows, but I sure wouldn't pay for it. The reason that I mentioned Open Perl IDE is because I thought it was great to have another useful free and Open Source development tool for Windows (and just maybe, Windows users would consider using more open source software in the future).

As far as *NIX development software goes, I use KDevelop or Anjuta for my C++, and plain pico for Perl.
