The majority of what that says is irrelevant. IE only supports tabs with a lame msn toolbar. IE blocks less popups than FF. IE has so much malicious content written for it its crazy. FF 2.0 is coming out which will blow away Avant and its inferior IE engine. Windows doesn't uncludea decent FTP client, if you open IE and ftp to a server theres no upload.
All is fair in love and war.
