Also no modern PDA supports 640x512 or 640x480 to my knowledge, which would at least be required to get a lot of amiga apps running.
No we just need 640x256 (Pal Highres noninterlaced) which doesn´t exists either.
But there are some devices with 640x240 screens like the HP jornada and the psion netpad, actually psion netpad is the formfactor i want but it lacks some hardware.
It´s to bad the highest res on the palm is the Sony 480x320 and the next set of palm will be arm7 based( not 68k compatible).
Anyway i don´t think anyone will make pdas with screens that are satisfactory to me, might just aswell do one myself.
DIY is the way!
