Plug In Launcher is a neat little program that activates when you plug your charger in or when you plug your headset in. So when you plug your phone in to charge at night it can load your ebook reader, your desk clock, run angry birds or open your music. Then when you plug your headset in you can get it to load your music or load up a cardio trainer type app. It is handy as it saves you hunting through your apps looking for the one you want.
