One thing I want to add about this article is that I started it in the last week of January, before Firefox 3.6 or Chrome 4 were released. In the first set of tests, Safari had the lead. The order was Safari, Chrome, Opera, Firefox, IE.
When Firefox 3.6 came out, it became a contender, but not enough to push out Safari (or Chrome 3.x). The new pecking order was Safari, Chrome, Firefox, Opera, IE.
A few days later when Chrome 4.0 was released, it became the leader, making the new lineup: Chrome, Safari, Firefox, Opera, IE.
At this point the article was ready to be published. In fact, it was put in queue Monday night. Tuesday morning Opera 10.50 was released - doh! So if you see any typos, I apologize, I've been pulling all-nighters to get the new Opera results in by today's deadline so as to not give you guys out-dated info. Now the order is: Chrome, Opera, Safari, Firefox, IE. This WILL change, it's only a matter of time, and not much of it.
Browsers are definitely one product that is NOT stagnating. The placing of these browsers changed four times in one month! Meaning that one month ago, Safari would have been our pick. Obviously, I have a lot of data that didn't make it into the article due to the release schedules. I can definitely tell you that Firefox 3.6 is a BIG improvement over 3.5.x - so I don't doubt their claim of a 20% speed boost at all. Also, Opera moved from a sad 4th place to damn near 1st when they brought out 10.50. Good job guys! That's a big improvement.
I have a feeling that the frenetic pace of innovation isn't going to slow down any time soon, especially with Europe getting a ballot screen. Exciting (if not exhausting) times for Web browsers
