Yeah to tell the truth, I think Microsoft has just been lasy scrunching up 3 processors together, hoping it'll bump up ratings, and improove speed. They haven't joined them together like a dual or trip CPU, they've just made them share resources so it'll kind of be like Pentiums Virtual CPU, except not virtual, so rather poor in some accounts.... at least Sony have made an effort
If you've seen that demo of the PS3, you'll know just how powerful the Cell processor actually is with its amount of inner cores. For instance putting virtual enviroments into real world video, like what they do in films.
Something else that amazed me was a leaf demo and they had all these leaves (thousands of them) blowing in a vortex of wind, and they said that the cell processor was so powerful, it could calcuate the position of every leaf and have a sound channel for each and every one of them simultainiously in full surround (5.1 and DTS)!!!
it'll be kewl when thats released on other platforms too, since the cell chip won't just be on the PS3 for very long.
Yeah an OS has to be on it in some form, but won't be like Windows where you'll see taskbars. It'll have a display going over the workings like the Xbox had with its virtual type world. Even the PS3 will have to use some kind of OS... no idea what though. Wouldn't run without some kind of one...
