I have my bundled get no additional cost and must say that I since my 360 used as a "normal" DVD player.
the running noise of the built-in drive are sound responsible in large part for the. both my old hitachi as well as my new BenQ drive are unreasonably loud. my new console with this external drive is much closer to the reasonable range.
together with the currently extremely low available HD-DVD's a strong buy recommendation for mini-price.
