Never left it and I've been surfing since UNIX FTP, Lynx and Gopher days - I used Netscape until IE caught up and have had zero problems - straight out the box it displays every kind of webpage, plays every kind of media - and I don't waste resources running antivirus or antispamware and have never caught anything nasty.
Maybe someone could point me to one URL which will cause trouble for IE6 ?
(I'm serious about this because I work in IT support - albeit low level)
