It does make the image look sharper, but for practical purposes it probably doesn't make a huge difference. But it does help when you output it using the TV out. Several problems with that. For one it requires you to jailbreak the device meaning each Apple update means you have to wait till that update is jailbroken. Two, last time I checked backgrounder and kikare (or whatever the second one was called) weren't 100% solid. 3) The iPhone's apps are likely designed around using the available resources since Apple provided them with a system where only one application runs at a time (besides Apple approves applications like their media player, telephone operations, etc..). See above post about the problem with jailbreaking. So far from the videos I've seen in your thread, yours seems to be the only one with the issue with playing music and doing something else. Is it not as smooth as the iPod/iPhone? Yes, but then again the iPhone came from the iPod lineage where its primary function was music (and later other media). While the n900 came from the tablets lineage where the purpose is all around functionality.
