After all I've read I'm very much against ATK. I think in the older Android phones it was great, but now the OS is so much better that it just causes problems (just my opinion). There are MANY threads on the Droid X page that talk about how somebodies phone is all of the sudden sluggish, or doing random reboots, then they remove ATK and all is well again. If you have battery issues, for my phone, rooting (used EasyRoot...it was easy) and then running SetCPU had a huge impact on my battery life. I almost always have 30 to 40% left at midnight when I plug it in.
