I've already seen some negative impressions on the browser, but sincerely, I think it's pretty fine. Granted, it might be a bit slow, doesn't support YouTube and has to render incrementally, but major sites (Gmail, Facebook, Digg, GBAtemp...) seem to work. Zooming is smooth. Also, it does seem to support many HTML5/CSS3 features, AJAX and Canvas (I will post compatibility results soon).
