Gemini: The Newest Thing In All Of Psion
By therefore founder, Martin Riddiford

So the battery is under the keyboard :
the most favourable from a component layout and ease of manufacture point of view was to put a large, flat battery under the keyboard
There is also a (smaller) supercap(acitor) under the display.
the removal of the battery from under the display has opened up space to use a supercap to assist the battery
Keys are compressed when Gemini PDA is closed :
We hatched an audacious plan to squash the keys when the device was shut, saving 1.4mm in thickness. This is done with magnets on the corners which compress the keys and hold the lid and keyboard frame together.
