If the app stops running, that's *fake* multi-tasking, and doesn't match my experience; I can't remember the details, but I tested it on a Nexus One, and the item I was looking at was gone, I had to scroll again. Also, I cannot go to last.fm on the browser, play some music, and do other stuff at the same time, can I? Anyway, what you do in Android is your problem. The point is that in Linux we need good PM *with* multi-tasking (not really an argument against opportunistic suspend, I think, but a clarification from Ted's comment) -- Felipe Contreras -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
