The configurations section will provide you with the major configurations that are the same across all handhelds. Obviously the handhelds will vary with the particular model. For example, the QWERTY series will have a physical QWERTY keyboard whereas the other models do not. Therefore, there will be no mention of a QWERTY keyboard within the configuration section. If you should have any questions, or find something I might have missed, consider writing me an [email] to let me know.
