Well, might be just my head, but it really seems to be faster...especially the browser (gmail is opening really quickly...) and the media player, who used to lag when playing first time...will have to use it more often to confirm it...also, might be just my impression, but pictures taken by the camera seem to be clearer...but this one I can't really compare right now...should have taken some pictures before updating...
So even though there isn't any new features, the performance improvement more than makes for it
