If you aren't familiar with the Tapwave Zodiac it is a touch screen PDA from 2002 or so that runs a Palm based OS. I has about Pentium Class processing with an excellent ATI Graphics system. As a PDA, it is pretty powerful and even had bluetooth support. It was intended to double as a gaming system and has four directional buttons, a joy-pad and shoulder buttons.
In my opinion the graphic system outweighs the processing capability. Duke Nukem Mobile is a First Person Duke game with great graphics, but shallow or constrained programming. Because it is Palm based it has ports of a LOT of popular games that run on it. I have ports of Duke Nukem 3D, DooM, Heretic, HeXen, and Quake. Because of the ATI graphics system, if the processor can run the game, the video can handle it pretty well. It runs Quake ok at 320x240, which sounds low by todays standards, but for a 4" screen it looks fine.

It runs Duke Nukem 3D at 480x320 quite well.

Anyway, I like it as a gaming system.
