And it serves only for technology demo. It can not run 68k binaries so it is better run AROS natively on x86 or m68 hardware (i.e. Natami if it ever gets released).
Neither can AROS on x86 so it's just as useless/useful as the PPC port.
99% of AROS software is open source anyway so the CPU architecture it runs on its largely irrelevant.
What AROS PPC does need is binary compatibility with MorphOS and/or OS4 software.
