I actually agree with Imaro, or at least the letter of his post -- 4E *can* be run (mostly) as a board game. Now, I don't think that is the design intent, nor do I think that most veteran players will run it that way, but it certainly can be: encounter to encounter (whether that's combat or some other systemic resolution -- that's for you, hong) with little or no concern of the continuity of things beyond short rests and long rests.
One thing I rather like about the new DMG is that, the offending paragraph aside, it does tend to give equal time to different modes of play. In discussions of adventures and campaigns, it provides about the same words and energy to purely episodic, kick the doors in style play as it does epic save the world style play. In the campaign section, it covers (albeit briefly) campaign styles from horror to S&S top anime/wuxia equally.
