IE have got very bad reputations for a very long time. Even if the latest IE version now has sort of, say speed advantage over other competitors though, there still is no point to use it.
Nowadays, having a web browser like firefox or chrome with tons of extensions, you can practically do anything you want. (e.g. I'm using firefox do email(simple mail), document management(zetoro), RSS reader (builtin feature), and a bunch of things else, and with vimperator, you can even make firefox as handy as Vim.)
So my point is even if you stuck with dumb windows, you don't have to mistreat yourself by using crappy, shitty IE, better solutions are out there.
