The Sony CLIÉ PEG-TJ37 is a personal digital assistant manufactured by Sony that was built to replace the TJ-35 and is a higher end version of the TJ-27 in the CLIÉ TJ series. While the TJ-27 had 320x320 color display, a built-in 640x480 camera, and Graffiti 2 input, the TJ-37 added built-in Wi-Fi and MP3 capabilities into the same package. Both are run on a 200 MHz processor.
