OK for the IT folks on here, if you want a browser that renders quickly, and I do mean quickly, Safari 3 is it.
There are a couple of things wrong that I've noticed, like it doesn't like rendering HTML that isn't spot on, but if you're coding HTML, it should be spot on anyway!!
As a test, I opened both IE7 & Safari 3. In IE7, went to
http://news.bbc.co.uk ... as soon as I hit enter, go to Safari, and do the same. I refreshed the page approx 5 times in Safari before IE7 had finished loading.
