I don't want to get involved in a deep and strenuous discussion, but I do keep Advance Task Manager Widget around in case I need to stop something that isn't running right. Instead if going into manage applications and force closing it, I just tap the widget and stop everything, but I am not under the impression I get better battery life or my phone runs smoother with it. I like to keep my options open, so do I need a Task Killer, probably not, do I use one, yes...but for the right reasons.
