Today, I finally did it. I finally deleted Advanced Task Killer. Ever since getting my Eris, I have been dependent upon it. I have in fact been obsessed with it, making sure I clicked the ATK widget to kill all programs before ever putting my phone to sleep. I was obsessed with battery life and the Messages App issue. Now, I am giving it a shot. My two biggest concerns are phone speed and battery life. My battery life has been fine, mostly because I shut my 3G off when I am at home or work. My phone speed has been lagging considerably, and I am hoping that deleting ATK, along with deleting some unused Apps and clearing the cache, will help keyboard lag and general app lag. I will keep you posted to see what happens. I am excited, I know that a lot of you have highly suggested not using Task Killers, and I am excited to not be bound by it. However after a week if I notice considerable battery life loss, and no considerable difference in device speed, I may reinstall it. We shall see!
