I uninstalled Xfinity TV Go as I never use it anyway, but the others listed above don't have the option to uninstall. They do have a Force Stop, but I'm afraid to do that. I did move every book to the cloud and uninstalled every single app I could uninstall except for four. I kept Fish Tycoon, Virtual Families, a color bubbles app that wasn't running in the background and my clock/weather widget.
