To be fair the multi-tasking on the iPhone relies on apps to use APIs. So until apps do, they don't work well. Granted I prefer the N900's multi-tasking since you don't sacrifice anything. But games should still pause when you navigate away. Since there's no point in having a game running at 100% when you can't control it. =P But I can see the value in the way the iPhone does it. But I guess it's that whole what makes a mobile computer vs. smartphone divide again. Which of course is up to each user's interpretation.
