Palm Tungsten T

The second Tungsten, the Tungsten T, introduced in November 2002 and known during development as the M550, was the first model to use Palm OS 5. The Tungsten T was designed by Palm engineers based in Arlington Heights, Illinois.

It has:

• 16 megabytes of memory,
• Texas Instruments OMAP (ARM) 144 MHz processor,
• built-in microphone for voice memos,
• dedicated voice memo button,
• vibrating alarms,
• standard 3.5 mm headphone jack,
• one front-facing speaker,
• indicator light,
• runs Palm OS 5.0, and
• is otherwise a standard Tungsten; see above.

It is 4.0 inches (102 mm) tall, 4.8 inches (121 mm) tall with the slider extended, by 3.0 inches (78 mm) wide by 0.6 inches (15 mm) thick, and weighs 5.6 ounces (146 g).

It sets itself apart from other PDAs physically by having a sliding lower portion; the bottom third of the casing can be slid up and down to cover or reveal the touch-sensitive Graffiti writing area. At introduction, it was US$499.
