Is it a watch, is it a PC, is it a PDA? Cartoon heroes Dick Tracy and Inspector Gadget never had it so good. This three-in-one device has all the features of personal digital assistants including scheduling appointments and compiling to-do lists, plus calendar and address book tools. Although it is a wristwatch, it is a big one, at 51.6 x 55.5 x 17.7mm, and weighs 52g. It includes a serial port connection (for the docking cradle), an IR port, four function buttons and a cursor pointer for navigation. Inside, there is a 16-bit CPU running WPS-DOS (version 1.18), 512KB ROM, 128KB RAM and 2MB of flash storage.
