I have read jamie's posts as well and while I understand (or at least think I understand) that he is concerned about user options being chopped away for the sake of "security", I really do think that the good outweights the bad when it comes to stuff like this.

I'm not foolish enough to click on a dialog that says "Click OK to secure your computer", specially if I'm browsing the web but I definately know people who would click on it without knowing the mess they are getting into.  As so, I think getting rid of this "feature" is for the general benefit of all.

Another thing to understand is that while there is complaining going on about Windows restricting users and limiting their options in an attempt to secure their computers, I believe this actually gives users more options.  They can now choose between having a computer running easily exploitable services and features, or having a tightly sealed system.  It then allows them to open up only exactly what they want, thus giving them the option to configure their system how they best see fit.

I like the thought Windows locking itself down and I think any software that can expose potential security threats should also be locked down out of the box.  When you buy new software, you generally don't know how to work the entire package which means you never truly know you have secured it correctly until you learn its every option inside out.  If the program is fully locked down, you know exactly what the vulnerabilities are since you enabled the settings yourself and you can better prepare for any exploits as you know the vector of attack your offenders would take.
