Actually, according to the OS X EULA (http://images.apple.com/legal/sla/docs/macosx105.pdf) "This License allows you to install, use and run one (1) copy of the Apple Software on a single Apple-labeled computer at a time." When I bought my Macbook, it came with an Apple logo sticker. When I upgraded to 10.5, a similar decal came with the software. Perhaps a legal mind could explain to me in what way sticking one of these labels to a Hackintosh would make it anything other than an 'Apple-labeled computer'...

The Cell in the PS3 is basically a PPC core and 7 DSP cores, though I believe they call them SPEs (Synergistic Processing Elements).
