While I don't believe that firmware updates really do anything to prevent piracy/homebrew as evidenced by the Wii and DS (other then causing a flood of posts here how the sky is falling, until less then a week later there's an update to get around whatever it is.), Nintendo is at least being smart this time in making you want to update by adding a lot of new appealing features as updates. On say, the Wii on the other hand there hasn't been a reason to upgrade beyond 3.x unless you wanted the SD card menu. Now, we do have hacks on the Wii to install specific IOSes to still play new games without updating, but I think it still makes a good point. Granted, Nintendo could just be being lazy since they could have included the shop, 3ds video recording, NetFlix, etc out of the box. But I think they purposely did it to make people want to update. It might not slow things down too much, but it's at least something.
