First, the PS3 needs to try harder at being a PS3.
Consoles can never be computers. The business models are not compatible. Refer to Microsoft's licensing woes with nVidia over the original XBox hardware. With the lack of tools and documentation, the only things you'll be able to do with the hardware will be roughly equivalent to budget x86 hardware, anyway. That goes for all consoles.
There isn't much in the way of community involvement, either, which is what really defined the Amiga. Public Domain (the only truly free kind of software) was the best thing about the Amiga long before Shareware and Linux became popular in the PC world, and the people who wrote the software usually had some decent design experience. Everything these days, even the GPL, has strings attached, and it's all just about code, rather than what you can do with it.
