You're not going to use it regardless I suspect. I on the other hand will use it because it will run the majority of my non-game applications without platform emulation. Applications that will fly on a 800Mhz PPC. Using an emulated amiga is missing the whole point, with just the AmigaOS between you and the hardware you retain the Amiga's legendary responsiveness.
And the Amiga was not "dead" when PPC was added and moving to the PPC itself was hardly done without support. It was well know that Commodore was planning to move the Amiga platform to HP's PA-RISC chips, but with the demise of commodore (and PA_RISC), the owners of the Amiga added official PPC support to AmigaOS 3.5 and 3.9, then the OS was fully ported in versions 4.0 and 4.1.
Just because you think that a change of hands should kill a platform does not mean that I should think the same thing. And yes, it is a hobby system, what is wrong with that. Just because a number of people enjoy using an updated version of a 1986-era operating system does not make them freaks, or retarded. They enjoy using a system that is light weight, yet easy enough for regular people to understand, and one that is different from the orthodox Windows/Mac/Linux triumvirate. I suspect you would be seriously shocked if you ever left your narrow web-surfing confines and visited a site like osnews, where many people engage in the heretical acts of discussing, using and building alternatives to mainstream operating systems.
Regardless of what you think about the Amiga, AmigaOS has survived the demise of many owners and it continues to improve, just deal with it.
