What would I gain from switching, exactly? :u
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.
Nicer looking pages! Chrome and Firefox have the latest support for all the coolest features with web design.
More features. Chrome has apps and such, Firefox has all sorts of neat extensions that aren't possible with IE
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 second that.
Internet Explorer has been my long time friend, and in the glorious journeys I have endured with it, it stood valiantly and without a doubt, I have never been infected from any virus. Ever. The only viruses I have obtained were my fault, not the browsers. coughisohuntcough (bitdefender 2011 internet security suggests using IE anyways)
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
