Cell Chip?

[itix]

Cell doesnt suit very well because of its multiple cores.

You may not have noticed but *all* newly announced or shipping processors have at least 2 cores, multiple cores is coming like it or not.

Yep.

The Amiga was always used a lot in creative computing - video, graphics, rendering and to a lesser degree audio.

Yes it was.

Cell is a perfect match for these sorts of apps.

But it is not a perfect match for MOS, OS4 or AROS. On the other hand there arent such software anymore except Blender and POV-RAY. Both available to LinuxPPC and other OS'es...

And before anyone mentions PS3... no, it is not an option. You cant create bootable PS1/PS2/PS3 CD or DVD without license from Sony.
