The Sony Clie TJ series were mid-range personal digital assistants produced by Sony, running the Palm operating system (version 5).
The Sony CLIÉ PEG-TJ35 and PEG-TJ25 were released by Sony in 2003. These models are identical, except the TJ-35 also offers MP3 and ATRAC playback capabilities with a headphone jack. Powered by an ARM iMX-1 processor at 200 MHz, these devices ran the Palm OS 5 platform, featuring 32 MB of internal storage (23M available for user data), as well as a Memory Stick PRO slot for additional storage expansion. Synchronization via USB and Infrared is also possible.[1] The case of these devices appears to be aluminium, but is actually a painted plastic enclosure, with an internal steel plate providing structural rigidity. At the time or release, these devices competed with the PalmOne Zire 71. While navigation on these devices could be performed using the touchscreen, as was common for many Clie models, these devices also featured a scrolling wheel offering easy one-handed vertical navigation, which could be pressed in to select items.
The device comes with a few applications:[2]
A bundle of trial software versions are also available on Installation CD-ROM.
MP3s can be played from Memory Stick/Memory Stick PRO using the skinable AeroPlayer. Files must be stored in /PALM/Programs/MSAUDIO [3] directory on the Memory Stick. MP3s with bit rates from 96 kbit/s - 320 kbit/s will be played.[4]
Additional codecs to support Speex or Vorbis were available [5] for free.
TCPMP could be used to watch Videos on this device. The files can only be played from Memory Stick/Memory Stick PRO.
The Sony CLIÉ PEG-TJ37 and PEG-TJ27 were released in early 2004, and improved upon the previous models with the addition of an integrated digital camera, complete with dedicated shutter button, and a manual sliding lens cover. The camera featured VGA (640x480, 0.31MP) resolution, and was only capable of taking still photographs. Like the previous models, the higher-end TJ37 also included MP3 playback capabilities, but now also added Wi-Fi for mobile internet access. Most other features and specifications remained the same as per the previous generation.[6]
