Microsoft, Adobe – Get Your Act Together

Having just read a post on one of my favorite blogs Attack Vector about the recent developments surrounding the new Adobe Reader 0day, here is the link to Matts excellent argument for all of us to sing the praises of open source or not so well known software applications that fulfill the same purpose as the over priced over vulnerable offerings from Microsoft and Adobe.
