Media queries in IE

Do you guys bother using a script such as css3-mediaqueries.js to enable media queries in IE6-7-8 or not?

My concern is performance. Although it’s only about 15kb, I wonder if it’s worth it.

If the styling is important to you in these browsers, I don’t see a problem using something like this. As you say, it’s a small file, and it it’s put at the bottom of the page, it shouldn’t slow up the load much, although I guess the styles may jump around a bot while it’s loading.
