Every once a while I do the following per Apple store genius' suggestion - toggle the task view, and delete every single apps in the background. then do a power off and on. And I just did so and found once I powered up, all the apps deleted in the background came back. I understand the so called apps in the background doesn't mean they are actually running in the background as they can mean they are in the history... but I thought in IOS8 i was able to rebooted to a clean list... Not sure if you guys noticed.... I think i'd call it a bug, no?
