Hear Hear. I look back at supporting Netscape 4 in late 90's as equally painful as supporting IE6 in late 2000's. It's difficult to imagine, but Internet Explorer was superbly superior during that time. For example, the Netscape4 window couldn't even be resized without needing to reload and redraw the page from scratch.
Not to mention Netscape was incredibly unstable. I remember Netscape 4 crashing roughly every half hour. IE was rock solid in comparison.
This was actually one of the things I was going to reply with-- it also crashed significantly less on Windows than Netscape 4 and ran faster up until Active Desktop started to clog the whole thing up.
No, IE was actually a much better browser in 1999-2000.
It crushed Netscape 4 even on web standards support. For example much of CSS was terribly broken in Netscape.
