Thought this was an interesting read, especially coming from windowsecurity.com
To me they seemed to leave out a key factor, and that is the incredible risk of zero day exploits and the security update/patch turnaround. This is where IE falls flat on its face in my book.
They seemed to hint that mozilla's frequent security updates at one point are a bad thing showing that its insecure, but to me the largest problem is getting the average user to install the updates. Chrome does this nicely by just plain updating without user interaction (but allows this feature to be disabled).
Anyone else have any thoughts?
