Hello all.... Just ordered my Pro today (Sat), anxiously awaiting its arrival next week.
I was watching the Initial Impressions video posted by AC and noticed a feature I have never seen on an Android phone until the Pro. I have had the DINC, Droid, Droid X and Fascinate.
In Task Manager you can not only kill apps, but you can add apps to a Auto End list that will kill the app(s) as soon as you turn off the screen. Its not ATK, but it has its purpose.
