Hi
OQ and HP have similar product based on Transmeta 1 GHz.
Amiga ColdFire V4e (333 MHz) PDA will be more powerful and run Amiga OS 3.9 software at full speed.
Unfortunately Motorola did not release stand alone V4e CPU (Vaporware), therefore the PDA is also Vaporware.
Another possibility is Amiga PowerPC PDA based on IBM PowerPC 405LP (Low Power), at 380 MHz / 500 MIPS.
