"I think we agree though that the biggest part of the security equation is will probably always remain the people usings the systems, no matter what they are." Yeah. Who knows... maybe MS gets it act together and redesigns IE to be more robust and security-oriented in the future. Today, however, the difficulties inherent with large company's decision-making and closed-code business culture are hindrances to making a better IE. "I still get major problems with firefox/mozilla not being able to parse very basic web code, even the latest version." That's strange. I've had no difficulties creating even rather complex and layered designs with CSSs. The most obvious problems to my knowledge are that different browsers obey the CSS standard differently causing fluctuations of few pixels etc. and not all browser versions support CSS2 since the standardisation is still under construction (or was when I last took a look at it). In any case Mozilla and Firefox act pretty much the same when it comes to interpreting html (them being based on the same design) and one can hardly argue that Mozilla is a new browser nor that it would suffer from usual "post-beta version" difficulties. I fail to see the relevance of the ZDnet article in this context. There are worms for several OSs out there. I think that is not the issue. However, running a Fedora Linux or HP-UX or whatnot as an OS greatly reduces the risks of being targeted in the world today.
