Gemini PDA reinvisions the Palmtop PDA form factor, bringing a real keyboard to a modern mobile device The new Gemini PDA is like a Psion 5 reimagined for the modern age. Among the currently available computing devices, there is no equivalent to the clamshell PDA's of old. Instead we have touch screen phones with large screens and soft keyboards. The keyboard is very useful, obviously, and soft on-screen keyboards don't quite cut it. Therefore one hopes the Gemini PDA might encourage other newfangled palmtop computers to appear.
