Give me a break, these are just more people's opinions...
>It's just common sense - MS is the main target of hackers. I'm not saying anything against the open source movement other than that it's probably easier to find holes in software created by a loose conglomerate of programmers (open source) than it is to find them in software created by a tight-knit group of professionals (MS). The reason there is a problem is because there are probably at least 10x more hackers working on the MS software...
>What is amazing is that you can easily automate these patches with Microsoft tools and keep up to date without worrying about it. That's what we've been doing and it works great without any problems...

I love your choice of words: "loose conglomerate of programmers" vs "tight-knit group of professionals"... No bias there.. ;)

That hackneyed representation of OpenSource programmers, the principal accusation in the first series of FUD attacks against Linux three years ago, has been refuted countless times, but it is an easy assertion to make off the top of one's head. Studies done when that FUD first appeared revealed that those who code on the Linux platform had better training, on the average, than those who code exclusively on WinXX. The percentage of coders holding a PhD was greater in Linux than on WinXX. (I recall this from memory, for I no longer have the URL) That waseasy to understand back then, since VB was an easy GUI-RAD to learn. I've noticed though, with the advent of Kylix and KDevelop, to name a couple of GUI-RADs, that more and more less experienced or trained coders are generating Linux apps. So, at the current state of affairs I would call it a draw, and expect it to remain so.
