That's not it. Those had roll wheels or something and no touch screens.
I have seen picture of the prototype somewhere. It was square blue prototype with big screen with shape like iPhone. It might not be in the design archive at all because it was R&D prototype.
SGI Irix was ahead of its time, and so were the Nokia Communicator.
Battery quality/video quality wasn't up to par for mobile devices. Some DVB-T smartphones were released. Also, WWW wasn't made for touchscreen (where capacitive touch requires more modification than resistive).
I'd say on the Linux-side, Maemo and the internet tablet (NIT) were ahead of their time, still limited given power efficiency, but better than Intel.
