I respectfully disagree. Not big on Safari fonts. They aren't the worst either though, so whatever. I'm probably going to continue using IE less than 2-3 times per month anyway, so it's largely irrelevant.
Really? Safari's font rendering is very clean to my eye, at least, the cleanest of all the browsers.
Anyway, I don't use IE that much either so from that respect it's not a big deal...but it's a new browser and that's something.
