Advanced Task Manager Pro
This is one app that I really like however I have been told by some people that I shouldn't use it. I disagree cause it helps me regulate my battery use and kills apps that are running that I can't see is running. It is rather self explanatory in it's use and you do have to option to ignore what apps you don't want to kill that is running in the background.
Below is some screen shots just to let you see what you are dealing with and to let you know there is a free version that you can test drive to see if this fits your mush have apps.

I'll agree with those that say task managers aren't needed, HOWEVER they can be useful if you find they work for you and your setup.
To each his own, and I've heard this is one of the better ones. Nice.
It got a lot of good reviews. Can't be all that bad. I may have to give it a whirl.
