Why do Linux people maintain that it is the best thing since sliced bread. What do you think will happen to Linux if it ever manages to become a widely adopted OS? It will get attacked just like windows because your maximum effect target will become Linux instead of windows same with any other OS that takes the place of windows. Once that happens you will come full circle back to how to pretect OS's and users and securing of your network. The operating system matters very little it is the adoption of that OS that determines attacks. Windows as an operating system is pretty secure it is the applications that are not, in my opinion security starts with the programmers until programming makes the necissary cahnges to program securely no matter what OS you are running it will be vulernable.

I find it intersting that just about every search engine returns the same result for Why are Mac's so expensive usually in the 5 results. Could it be that people actually search for why macs are so expensive or possibly this is a popular article or web site that would return a high ranking result from any search algorithm? Do your own research 2 articles on the first page of several serach engines returns results for macs, the rest have to do with microsoft windows and regular home windows that you may be staring out now.
