Or I'll be flipping through the People app looking for contact information and experience major lag when changing which information tab under a contact displays. If I kill the extraneous tasks when this happens (e.g. Browser, The Weather Channel, Facebook) then everything is bright and snappy again. I can't disagree with the original post, which was excellent, BTW. But my perceived experience on the Sprint Hero suggests that the task killer can be useful.
