High Quality Content by WIKIPEDIA articles! The Clie PEG-NX73V is a Personal Digital Assistant (PDA) made by Sony and was made in the form of a Mini Tablet PC. The NX73V is essentially the same device as the NX70V but with some minor changes. Most notable is that it accepts Compact Flash cards from other manufacturers. Although a minor change to the 70V, politically it was a huge step for Sony to allow the use of Memory Cards other that the "Memory Stick".
