Im am posting this from the xbox beta IE and it runs fast and smooth so far. Only 1 crash ive had. I give it a 8 as of now good features and all, but lacks possibilities. With out flash and only support of html5 (html5 is scarce to find videos etc; that are supported) is cannot do to much. Not something you would use for video/music browsing but its something new. If you have the beta tell me what you think if not tell me what you would expect or want/hope about this update.
