I installed longhorne beta on my computer last night which naturally wrote over my IE7 and the first thing i noticed is that when i went to my IE explorer it looked very much similar to seven, so i reckon the new version of IE is just getting ready for the release of vista which I must add, is very very nice. im updating to the new beta again very soon, just a friend already had the longhorne version on dvd and i couldnt wait. me and my lack of patience.
Take a look here
