Bulk uninstall applications I like to try out lots of apps. Often a site like Lifehacker or Droidlife will feature several that are similar in functionality and I will install them all in order to compare features.

That leaves me with lots and lots of applications that I end up not wanting to keep. Unfortunately, I can only uninstall one at a time.

Is there an app or method that would allow me to uninstall a bunch at a time?
There are tons of apps that do batch uninstalling but here's a simple free one that I know works: Uninstaller Pro 

A lot of the more full featured app managers also have a batch uninstall option.  I like to consolidate functions into as few apps as I can.  Now I use SmartBar which has a good app manager with batch uninstall.
