However, I find Opera is *so* superior to IE or any other browser that I find it worthwhile to use Opera as my standard and use IE on those less than 5% of the sites that do not render correctly with Opera.
Me to...I use it on both Linux and Windows. And most of those sites can be rendered correctly if you change your browser identity to MSIE 5. Some sites that have a hang up when they see Opera work just fine when you change that setting. (And like many of these settings you can do it from the menu Quick Preferences...on the fly!)
