I've been in the IT field since '92.
IE can be customized also:

From all the hype I've seen about "better this, cooler that" they are all about the same. OK! so Mozilla is open source. What does that do for my browsing? am I now going to spend all my surfing time - coding this 'lil bitty gotta have feature' or just surf? If I am a hacker it would be easier for me to figure out brower code for an exploit.
For all the hype I've seen with the browsers, I stick to IE. Never had a problem, and support is easy and quick if anything does happen. I've never had any exploits hit my system through IE, because I keep up with ALL OS patches. And THAT is the key - not the "browser of the day".
I have not really seen anything that makes me go "wow!" in any of the other browsers out there.
