Also known as the HTC Magician, the S100 is a Windows Mobile 2003 device with a few tacked-on enhancements.

Pluses:
- OTA sync with Exchange Server
- Bluetooth
- Display rotation (only 320x240, but nevertheless useful)
- Charges via USB
- SDIO support
Minuses:
- Bad ergonomics (UI, size, weight, shape, etc.)
- ActiveSync is very slow over GPRS, and unlike the Blackberry there is no attachment conversion - get ready for a hefty data bill.
- Crummy battery life (and sub-standard camera quality for a 1.3Mpixel)
- Poor audio (sub-standard microphone and speaker)
- Spends a lot of time showing an hourglass.
