We're not going to equip [the PS3 with] an HDD by default, because no matter how much [capacity] we put in it, it won't be enough. The next step is definitely network drives. With the Cell server, they can be accessed from anywhere, via network. Whether it's your own house [or] your friend's house, you can access the [network hard drive] anywhere. That's the kind of world we're imagining. But there are still some issues if the machine doesn't come with an HDD. So this time, we've added a 2.5-inch HDD bay so that users can equip HDDs, such as 80GB and 120GB, even though that's still not enough [capacity]. Although a network drive would allow for terabytes of storage, there's still the necessity to run an operating system offline. A hard drive for running an OS will be required for [the PS3] to be recognized as a computer.

KK: Linux is legacy, but it will be a start. In the case of the Cell, operation systems are applications. The kernel will be running on the Cell, and multiple OSes will be running on top of that as applications. Of course, the PS3 can run Linux. If Linux can run, so can Lindows. Other PC Operating Systems can run too, such as Windows and Tiger (Max OS X 10.4), if the publishers want [them] to do so. Maybe a new OS might come out.
