I’m not sure how recently it was released, but ArsTechnica (those who matter) have just reviewed this, so I thought I’d try it out.
I ran the original beta a while ago, and although I liked it, it was laggy on my machine, even more so than Ie in some cases, and it crashed a little intermittantly.
I also found a few small problems with the rendering, but they were just niggles, and nothing like as bad as the IE8 rendering system.
The look hasn’t changed at all, and that’s a good thing, I feel, but it has sped up, and I can’t find the rendering issues I had before, so I think it’s all good
I’m writing this post on Safari, and it’s working fine. so it’s all good
- I’ve included a screenshot, mainly because I’m playing with the wordpress Gallery feature, but also because it looks pretty good. The change in the submit button from the other two, bigger browsers is brilliant, I think it looks 10x better
Although I’ve only used it briefly, I think this could possibly be a competitor to the greats, like IE and FF

Safari on Apple is still better, though
Most likely, but it’s still pretty cool on Windows
