"Why isn't the PS3 broken already?" We hear this every day. Someone somewhere thinks they can write a better media player with HD support. A guy wants to release his game but needs the RSX for the amazing graphics it can generate. Why can't we just tear open the PS3 solder a few wires and be done with it? The answer is both simpler and more complicated than you might expect.
The PSP, the Wii, even the Xbox 360 have all been hacked and can run homebrew applications so everybody thinks "the PS3 should be just as easy." The PS3 in some ways is as easy, in fact easier. No other console let you install Linux and run anything you want to. Sure Linux on the PS3 is great. You can write your own code and use it. You have the largest collection of applications anywhere (thats right, WAY more than Windows). It's all free (or at a very low cost).
But it's limited. You can't touch the RSX (The very powerful graphics chip in the PS3), you can't use the full hard drive, and nothing is really optimized for the PS3's fantastic Cell processor, this means that what should be fast and easy tends to be slow and cumbersome. In fact, DVD playing which can be done on any modern computer is a monumental task in PS3 Linux."
