I'm a Safari user myself but then I'm also a Mac user.
IE on the Mac is a real POS, really slow and buggy. It is no longer made for the Mac and the most recent version is version 5 which is just a bad port of the Classic version.
What gets me is how many Mac users still use IE instead of the Mac's default browser Safari. When I ask them why they usually say something like how else would I surf the internet?
New security problems with IE released today.
