Not at all. It is still closed down like other consoles are. It is no more of a computer than the ps2 was. It is not a computer for me unless it comes with keyboard + mouse and is open for bedroom programmers. Sony seems to have closed it down so that linux cannot take advantage out of the 3d accelerated gfx and so on..
(You could almost say that the PS2 was like the Amiga, because of all of its custom hardware)
Isnt that the case with most consoles?
It's pretty much the most powerful around at the moment.
The performance tests so far suggest that it is really slow compared even to the cheapest pcs of today. Though the code is not yet optimized, but i doubt it will make that much of a change.
Do not believe the hype! The ps2 was also claimed to be powerful enough to do realtime graphics of the same quality as that days 3d rendering programs. And yet it was less powerful than the modern pcs of that day?
