The HP Jornada 720 (Rating: 0)

The HP Jornada 720 was one of the most advanced handheld PCs around the year 2000 — essentially a precursor to later keyboard-equipped smart devices, but with genuine PC-style capabilities.
In terms of hardware, the Jornada 720 runs on a 206 MHz 32-bit Intel StrongARM SA-1110 processor, paired with 32 MB of SDRAM and approximately 32 MB of ROM. For its time, this was a solid configuration, capable of running Windows CE (HPC2000) smoothly. The device measures roughly 189 × 95 × 34 mm and weighs about 510 gramsincluding the battery, giving it a sturdy, compact clamshell form factor.
The display is a 6.5-inch color screen with a resolution of 640 × 240 pixels and supports 16-bit color (65,536 colors). It features a touchscreen operated with a stylus, complemented by a comfortable three-quarter-size keyboard, which was one of its strongest advantages compared to many other PDAs of the era.
For connectivity, the Jornada 720 includes an integrated 56 kbps modem, IrDA infrared, an RS-232 serial port, and USB connectivity via a cradle. Expansion options consist of a CompactFlash (Type I) slot and a PC Card (Type II) slot. Additional features include a smart card slot, stereo speakers, a built-in microphone, and a 3.5 mm audio output jack.
Power comes from a removable lithium-ion battery, rated for up to 9 hours of use, which was impressive for a device in its class at the time.
