Size was my primary focus and then current features such as mega pix camera and mp3. Have been less then wowed with some of the functionality, but would make the same purchase again. Did I mention that almost everyone makes comment and it's a great way to open conversations with people. Well, they usually initiate. Seems as if all anyone cares about these days is the size of ones equipment and how nice it looks. It feels good in the hand and people can tell how enjoyable it is to communicate with by the smile.
