Internet Explorer 7.0

Windows automatic updates keeps prompting me to install IE 7.0 for Windows XP. Any thoughts on whether or not this is a good thing? I've had bad experiences in the past when it comes to migrating between versions of IE, and so far IE 6.0 is working just fine for me.

Looking for the collective wisdom of my friends list--hoping someone out there will know if this is a really bad idea or not.

Thanks.

ETA: Well it was an overwhelming thumbs-down from those who commented. Thanks for the advice.
