According to A Taste of Froyo: Google Android 2.2 Explored - AnandTech :: Your Source for Hardware Analysis and News, Froyo will have a native task manager. I didn't know of this until this article. Now, given how Android caches inactive programs and ends them when memory is needed (and the universal advice of getting rid of your task killer and how it's not needed to save battery life), why did Google decide to include this? I can't imagine it was ONLY for force closing when an app is behaving erratically. The article even says it's there for "for those dire times when every megabyte counts." I'm woefully confused; is this really needed?
