Moving forward, I hope Apple will get rid of the optical drive or offer an option to replace it with a 2nd HDD.
For those of us without excellent internet connections, it's the only feasible way to get HD movies.
Obviously circular reasoning aside, the other feasible way is to spend more time on a slower internet connection. Under 24 hours on a 2Mb/s connection for 20GB isn't prohibitive, unless you're looking to stock your hard-disk for a trans-Pacific flight.
