The lip of the Droid is for all types of activities. You can use the corner of the lip to spin on the conference table during meetings. You can use the lip to help level a desk phone that has a broken stand.
You can use the lip to even make art! How you wonder? Take the case off and use the accumulated lint and dust to evenly sprinkle on a piece of paper and then use a highlighter to color over the paper giving you several layers and depth to your art.
My daughter even uses the lip as a soother for her gums when she is teething! (yes I have insurance.)
