Internet Explorer is out in final form. The link above will take you to a download page at FlexBeta.
Oddly, the first available copies were from Yahoo and bundled with their mail app and some other things. FlexBeta's download page came up sometime after Yahoo's. There does not yet seem to be an official page at Microsoft.com, but I will bet they fix that in a hurry.
For those of you who wait and have automatic updates enabled in XP, you will have the new browser version pushed to you, unless you don't want it and sign off on it. Frankly, I can't see any reason not to get it. IE 7 is safer in many ways and by all accounts performs better than it's predecessors in nearly every way. Plus, it adheres to standards such as those for Cascading Style Sheets (CSS) much more closely.
