All I can say is it's lightning fast on Vista though IE7 was no slouch either, on a clean install, not even any security loaded. Compared to FF3 on XP though, IE8 beat it hands down. Only reason I didn't try IE8 on my XP was it wanted to download updates and run a Malicious Software Check and I'm not ready to trust it yet to be error free using my production rig.
