just downloaded and am using right now. so far it seems pretty nice. interesting design, though i don't think there's a progress bar or any sign of internet activity whatsoever with it, so you wouldn't know if the page was still loading or not.
Edit: just found the progress bar... which is what is causing the browser to be kinda sluggish. i don't like it very much. design is nice, but just seems slow, like sometimes the page seems like it's done loading, then my cursor says the window is busy for like 2-3 seconds, then it says the site is loaded.
