the sharp wizards, if i am correct, are sharp's high end electronic organizers... i remember when they first came out, models ran as much as $500!, but nowadays, they just can't compete with PDA's... i suppose they really do perform the same functions as PDAs, but are more difficult to use, although some did have styli and touch screen pads. they're nothing more than glorified electronic organizers, sort of a bridge between the pocket casio-type organizers and PDAs
