All the more reason for Amiga OS to move over to x86. Amiga was designed as a desktop OS.
I'm not sure if you could poach a lot of AROS to speed up the process. Let's suppose it takes ten years... In ten years PowerPC (available to us) might advance one more generation, but x86 will advance probably six generations.
A computer is your entry point to the digital world, it would be nice to have a nice operating system to put on it.
It actually doesn't bother me if the two PowerPc OSes never come to x86, AROS seems to be gaining momentum and Windows is looking very one dimensional in it's approach. We may look back at this time, "That gawd awful Windows era."
