Safer browsing. I know you said you haven't gotten viruses from using IE but there are so many ways to exploit IE that it isn't even funny.
If I've never experienced an issue, though, and don't do anything dangerous, that really doesn't matter. IE, for me, has proved to be reliable.
Nicer looking pages! Chrome and Firefox have the latest support for all the coolest features with web design.
I've never once seen a difference between any site I visit in internet explorer and Chrome. And the browser of Chrome itself bothers me, with the tabs way up top and the address bar beneath it. So offputting. :c
And chrome and firefox are faster, I know you said that you didn't notice a difference but I can tell you that there is a change, or you're some sort of odd case where the performance didn't increase for some reason.
I'm aware they are faster. Chrome is quicker by, at most, several moments, though. I'm rarely in a hurry to reload the forums, though, so it doesn't matter much. But I do use Chrome when loading a large page with a good deal of information since Explorer can be rather sluggish in those cases.
Did you two know that the German Government send out a notice to internet users telling them to specifically not use IE because it was unsafe? :o
Facist conspiracy! They just want us to use the Führer Browser so they can build their army again! :C!
