I don't doubt that it can be a good approach to develop certain applications for Windows in Perl.
It's more like a question I'm asking myself why I never got in contact with Perl when using Windows. All of the applications I use on Windows are either binaries (probably written in C, C++, C#, ...) or java-based.
On the other hand on Linux I often see tools written in Perl. Most of them run on the shell and don't provide a GUI. So maybe that's the main reason here: GUI development isn't that easy / good / advanced in Perl.
Don't get me wrong: I'm not stating that developing Perl on Windows is bad, I'd more like to state my own experience and maybe get some input from others to understand if I have some misconceptions there.
