Poor battery life has been a nagging issue for the iPhone since the beginning. The added processing from multiple concurrent applications would only make the situation worse.Paul C.http://recursivedescent.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-893005668131085829.post-16109727958013944412010-01-07T21:30:32.965-05:002010-01-07T21:30:32.965-05:00Personally, I think Apple wants to do background apps in a different way than other mobile OSes. For example, instead of running the entire app to stream some music in the background, they might allow you to define a helper service that connects up to your server and plays the music. For periodic tasks, they could allow you to set timers and run limited tasks.<br /><br />As far as GC goes, they already have a mechanism for killing apps when memory runs low. I would suspect that whatever they do with background tasks, they would use the same mechanism. Thanks to the way launchd works, any tasks killed would be automatically restarted as necessary. Takes care of the memory issue and the user probably doesn&#39;t even notice unless that task was what was streaming their audio.Dennishttp://www.blogger.com/profile/08416102789583927859noreply@blogger.com
