I'm just trying the new Beta version of Goggle Chrome for Mac.
It's very much a beta. For example there's no way of setting default fonts and text size. But one thing I must say: it's very fucking fast! Impressive. Including one of my standard sites, which on Safari for some odd reason takes like half a minute to load (the first page), in Chrome it is near-instant.
And from what I have seen so far with a trek through my most used sites, the rendering is really nice, pages look good and neat.
