Well, you already have WWF, Angry Birds? (though I haven't played it in a while). Docs to Go really is worth paying for, especially if you save something to Google Docs or a service like that because you can update and then sync with your phone. The LJ app has gotten better and doesn't crash as often. And I like SketchBookX because it's nice an simple when you need to make a diagram on the fly. I just realized the apps I use all the time are all works specific, so that won't help you much. Unless you need a customizable bar code reader, then ZBar is really good.
