I'm more interested in the PDA comment, about Amiga OS 4 booting on a PDA currently, at 240x320.
That must mean that OS4 is also compiling for ARM based architectures, unless someone has made a PowerPC based PDA. It might not be optimised that much ... the only thing it would need is software. Bum.
Anyway, that bodes well for porting to other architectures in the future.
