Sony states:
The operating system has also yet to be clarified. The integrated Cell processor will be able to support a variety of operating systems (such as Linux or Apple’s Tiger).
A very interesting proposal. It’s not surprising that they would be supported, especially considering who developed the Cell processor. It would be interesting to see if Apple would create a Mac OS X distribution for the PS3. It would have some potential of increasing the user base, and providing a new avenue to showcase the OS’s features and capabilities while not really infringing on the computer business (people aren’t likely to trade in their PC’s for PS3’s just yet). Apple may have had this in mind for some time, just take a look at technologies such as Inkwell, VoiceOver, and of course Speech (which has really been around for several years). It’s perfect for the PS3.
