The Psion Siena — Compact EPOC Handheld
The Psion Siena, released in 1996, was a compact handheld running EPOC16 — a smaller, more affordable alternative to the Series 3a that sacrificed some keyboard quality for improved portability. The Siena’s clamshell design with a touch-sensitive screen made it distinctive among handhelds of its era, and its suite of built-in Psion applications gave it genuine productivity capability despite its compact size. The Siena targeted users who found the Series 3 too large while wanting more capability than simple organisers offered, occupying a niche between pocket organisers and full handheld computers in Psion’s product range.
