Okay, so my friends have been the targets for my boasting about android and how awesome its going to be (because ive been hanging out here since im getting my droid soon) and i guess one of my friends finally broke, and went and got himself an android phone today. He got the Hero, and i immediately told him to get a few key apps, such as handcent, ringdroid, and the dolphin browser. he also told me he was going to get an app killer, saying that it will keep his phone running smoothly, and to conserve battery life. I told him that android was optimized to NOT kill apps, but he said he did his research on it and said something about "booklet" (app maybe?). I have no idea what that means. Anyways, I just wanted clarification on what exactly happens when you kill an app in android. Ive heard that it just makes the phone eat up cycles anyways because the OS boots up the app again whenever the app needs to do something or other. Like I said, I just wanna get my facts straight, so I dont look like an idiot when im arguing to him about android.
