I'm realizing more and more as I go through the app store that there are some apps that really need to run in the background like radio apps, and one I saw that allows you to track your iPhone via google maps on your computer. This would be a brilliant feature for catching a thief or if you lost ur phone. However without the ability to keep it running it is rather useless. I have to think that apple has thought of.. Their solution is great for things like IM but doesn't cover these other concerns. I hope that this is much like when apple said they would only do web apps to tide people over while they worked on the app store.. Perhaps there might be some form of task management app that listed running apps and a simple red quit button. Also I think that any app that wants to be able to run in the background should have to go through a tougher review process so that apps that don't need the feature won't bog down the phone by running in the background.
