The Sony CLIÉ PEG-SJ33 was a Palm OS based handheld "Personal Entertainment Organizer" released by Sony in 2003.
It was released with a heavy multimedia focus, one of its key features being the inclusion of MP3 player software and built-in stereo sound hardware (a rarity on Palm OS devices in 2003).
The PEG-SJ33 has the same HiRes screen as the other low-end colour CLIÉ models.
