And I quote
Within 24 hours of the official launch on Tuesday, there were over 2 million people using Firefox 2, and we were seeing a peak rate of more than 30 downloads per second from our website.
I love it to see IE and in particularly IE7 being beaten and I cannot wait for the day that Firefox is used on more user desktops than IE (wishfull thinking on my part, I know)
Update: Christopher Blizzard said it a lot better than me …
