First off, I'd like to say that I use Win32. (For the purists -- face it, it's on 98% of the machines out there. If you only think that Perl should run on 2% of the world's computers, you can go ahead and stop reading now.)

Unless you were aiming to be deliberately provocative, that parenthetical remark added no value to your message. It gave a screed-like quality to the entire message, tainting it as scorching a few grains of rice in the pot ruins the whole batch. It belies a lack of care and concern.

Others have spoken to the substantive matters, so I won't recapitulate them.
