dump IE
Another op-ed about how Internet Explorer is completely insecure, and if you hate spyware, it's time to switch to Mozilla Firefox.
Fact of the matter: IE is old. In fact, in a techie world governed by Moore's Law, it's downright ancient. To mix metaphors, why-oh-why would you keep driving a 1976 Dodge Colt when you could have a 2005 BMW M4 for free?
Firefox is fast, standards-compliant, available for many platforms, and because it is not intertwined into the OS, does not make your OS any more susceptible to Trojan horses and spyware than it already is. I can't think of any reason to continue using IE, nor any reason not to use Firefox.
