Personally, I happily use Windows and Linux. Same with Open Source and proprietary software products. Wouldn't give up either world. I am guessing any Perl programmer is informed on Open Source matters on some level.
Personally, I find it irritating every time a subject involves non Open Source Perl programming, you gotta wade through all this irrelevant to subject at hand stuff about Open Source. Heck, people will even mod your post down for discussions about Proprietary Systems???
