You know IE is the only browser that DIDN'T conform to web standards, right? FireFox, Opera, others, and (now) Chrome all conformed to web standards...IE was always the red-headed step child that didn't conform, and web developers had to code around IE's quirks...which is why most web developers ****ing HATE IE with a passion. I don't really believe that you were actually a web developer when you say that IE was the one doing things right (because it wasn't).
Nowadays they've gotten better and actually started conforming to standards...but it still has oddities and is still the odd-browser out.
