It's a really good write up. I love how people instantly try to vilify apple for it's decision, not to allow third party background apps when a majority of Apples own apps for the iPhone do not use background processing. Perhaps simply it's a resources issue. Battery is the resource that everyone thinks of first, but like any small computer system the iPhone has limited CPU and RAM, push those and you are going to kill the battery even faster.
