While the TJ25 is lacking in multimedia capabilities, as there is no headphone jack or speaker, so you won't be able to listen to music, for example, on the device, the TJ35 has a headphone jack and speaker. In terms of music, the TJ35 has Aerodrome's AeroPlayer MP3 player.

Applications bundled with the TJ25 include Sony's Clie Launcher, a very useful replacement for the traditional Palm OS launcher, a back utility, image viewer, world clock, and file manager, as well as some games, utilities and trial software. The TJ35 adds Picsel Viewer, which lets you read Microsoft Office documents, which you can do with Documents to Go on the Tungsten E.


Clie Launcher

The TJ series, unlike the Tungsten E, comes with a removable battery. For syncing and charging, it offers a dongle, which attaches to the bottom of the PDA and connects to a USB cable and AC adapter. A docking cradle costs $30.

Sony's TJ series offers two solid units that won't overwhelm business users with the multitude of functions offered by the company’s higher-end devices. In terms of their chief competition, the Tungsten E, the TJ35 measures up better. The TJ25's minimal amount of memory, lack of sound and a Microsoft Office document reader, limits its appeal. Another problem is that it lists for the same price as the Tungsten E, which offers all these things and more. The TJ35, which compares more favorably to the Tungsten E, beats it out in some areas, such as a faster CPU and removable battery and doesn't in others, such as the Tungsten E's more robust Microsoft Office document syncing and brighter display.
