The title of the post pretty much says it all. The Best Buy Mobile guys wouldn't let me and my wife leave without installing Advanced Task Killer on both of our Evos. I didn't feel like arguing, so I just let them do it. However, as soon as I got out the door I uninstalled it from my phone. I left it installed on my wife's Evo just to do a comparison, and without it installed I got WAY better battery life than she did (of course, I've uninstalled it from her phone now, as well). Furthermore, they didn't even know how to use ATK properly and had you check the apps you wanted to leave running when the directions for ATK clearly state the opposite. Anyone else run into the BB Mobile people forcing ATK on you before you could leave?
