It's pretty cool. The free download is right here.
It's faster, got some nice features on it. I especially like the fact that I can chose my own "skin" for the browser and have as many tabs as I want. If I want a tab to be it's own window then I can just pull it out or rearrange them how I want. You can also take a window and turn it into a tab by clicking and dragging on it.
Try it out, I highly recommend this browser.
