Please don't insult us. I am a programmer, I have programmed for Unix/Linux mostly, I know allmost everything about Operating Systems, the history of Linux etc... What the hell makes you believe that Linus was thinking security first when he first implemented it. What makes you think that MacOS X is designed security in mind. Please be reasonable, you are talking to technical guys here. Only political people would claim that. However I understand you if you repeat what you read. Nothing in Unix or Linux has anything to do with special security. The only good thing about Unix was this super user separation, and for that windows xp had the same. If you would consider Windows 95 or 98 I could understand, but XP vs Unix? Most of the security problems come from services with ports open by default. Almost all linux services has security patches, you probably don't hear about it or that you just don't read about them.

The only problem Microsoft had is that opening these ports by default even though many home users didn't need them. That's where Microsoft made a serious mistake, that's the only place you can really criticize Microsoft fairly.
