IE7 hasn't been released as part of Windows Update yet, but its usage is up to 6% of all IE users on the Random Pub Finder. Saying that, FireFox 2 is being used by 38% of all FireFox users. I reckon that is down to the techy nature of most FireFox users. Funnily enough 20% of our visitors are now using FireFox, which is pretty astounding. I'd guess we've had quite a few techy people visit recently due to the coverage we've had.
