The 3c will cost £340 for a 1Mb RAM and £400 for a 2Mb RAM version and retains the features of the 3a, adding 115kbps infra-red communications, an improved suite of applications, revamped user interface and a modish case redesign. It boasts two expansion slots.
The Siena will cost £170 for a 512Kb RAM model and £230 for a £1Mb RAM version. It weighs 0.2kg and has been built to fit in a shirt pocket. Aimed at a wider audience than the 3c, it comes in a range of colours and case designs.
Both palmtops include QWERTY keyboards. The 3c has a 480 x 160 greyscale screen and the Siena has a smaller 240 x 160 greyscale display. The 3c is powered by two AA batteries with a two to four month life, and the Siena requires three AAA batteries, giving an average one to two month life, according to Psion.
