The first interesting aspect of managing your resources is that every combat matters - not just the one's you can win easily - because if you aren't careful about how you cast your spells, you'll have fewer for the next battle. A critical hit might not kill a powerful fighter, but it might force a difficult decision about whether or not to use a daily healing spell. Also, it's pretty standard for an intelligent adversary not the sit around and wait for PCs to sleep before counter-attacking. That means that the descision whether to sleep and where also has to be taken seriously. The significance of resource management goes far beyond just resting for the day.
When facing a fortress of evil bad guys, the sum total encounters in the fortress need to be considered in 3E because you might get through only part and then the fortress will counter-attack. In the proposed 4E system (according to the design goals) it won't matter - the PCs can go through all 1000 encounter areas and if a single one doesn't become a life or death situation, they're essentially all a meaningless waste as the effectiveness of the PCs is reset to 100% each time. There's no grimace from the players when a kobold hits the party fighter with a critical because he can just get his hitpoints back at the end of it all. (And if he can't then we're back to the 3E rest situation).
