The only reason you should ever use Internet Explorer.
The sole purpose of IE
The best part about Internet Explorer is that it forced companies, such as Mozilla and Opera, to make their own browsers, which completely and utterly blow Internet Explorer out of the water.
Download Opera/Mozilla plz.
IE is buggy, has many security holes, is slow, supports ActiveX so websites can install their XXX dialers on our systems, and finally, it's not standards compliant, so 80%+ web pages have sloppy HTML which doesn't work with standards compliant browsers, only IE. How convenient.
