This isn't massive news, because any CPU can, in effect, run any operating system if you strip it down enough, etc. However, Sony says that the Cell "new multi-core 3.2GHz Cell processor developed jointly by IBM, Sony Group and Toshiba will support a variety of operating systems, such as Linux or Mac OS X Tiger." Notice they didn't say it will run Windows. This is a very telling, oversight. It's so cute to watch these guys dig at each other all the time. It's like Mean Girls.
