Well I am astounded. As of the time I answered the poll, everyone had answered firefox. Way to go forum people!
Yeah, I had a look at IE7 and it's just the current MS trend. They took an established simpler program and put in a bunch of big, clunky buttons and totally obscured the original layout.
Plus Firefox has some fun extensions, like the google customizer which among other things is supposed to stop google from being able to track your every move. Yeah.. I'm just not cool with the idea of them keeping track of every search I've ever performed and storing it, FOREVER, with no oversight or anything.
