Both machines – the CliÃ© TH55 and the CliÃ© TJ37 – run Palm OS 5.2. But while the more consumer-focused TJ37 is based on Motorola’s ARM-based i.MXL processor, clocked at 200MHz, its high-end companion is based on Sony’s own Handheld Engine CPU. This runs at between 8MHz and 123MHz, depending on load, in a similar fashion to Intel’s SpeedStep technology for mobile Pentium processors.
The TH55 ships with 32MB, as does the TJ37, but while all of the high-end machine’s RAM is available to the user, only 23MB of the TJ37’s memory is accessible.
The TJ37 sports a 320 x 240 16-bit colour display, while the TH55’s panel runs to 320 x 480. Both feature a 640 x 480 digicam, backed with still and video capture software, along with the usual array of Sony-bundled music and movie playback applications, including the AeroPlayer audio player and Kinoma 2 for video.
