There's so much talk on the site about task killers. Having just gotten my Droid 2 days ago, I'm a little confused. I know it is controversial here, but do I need one? Is there a downside to having one? (I'm not the "rooting" type, just a happy everyday user who wants to keep things as uncomplicated but functional as possible.) Does a Task Killer uninstall the app so that you have to go back to Market to re-install it (and maybe pay for it again) or does it just stop the app from running? I downloaded Droidlive and found in "Managing Apps" that it was still running even after I clicked it to stop the music and left the app. Is there an easy way to stop an app from running without a Task Killer for a very non-techy type like me? If I need one, what is the most simple yet effective Task Killer for an overwhelmed newbie? (I'd prefer a free app since I'm experimenting.) Hope that's not too questions. Sorry if I missed this info elsewhere in my thread search.
