I completely abandoned PPC. I think it's the worst CPU ever made. IBM conned Apple into using it originally, and they finally got smart and switched to something much faster. I was stunned when I heard that the next generation Amiga was going to be PPC based. What a mistake that was. That limited the sheer number of people who could have been exposed to the great Amiga OS. Had the next generation Amiga gone x86 based, it would be at least (if not more so) popular as Linux is today.
I have to agree with you on your perspective about PPC processors. So far I'm enjoying AROS x64 and it's latest SMP capabilities. I often wonder how far OS4 would have progressed in that regard had an x86 processor been selected back when the next generation Amiga was designed....I suspect OS4 would be at least as mature as AROS x86 is now and probably even more advanced. A lot of OS4's momentum was lost and will never be regained by going with the PPC architecture. I'm looking forward to doing some AROS development and hope to port some classic Amiga apps to AROS. I took a stab at some OS4 development around 2008 but there were just too many obstacles to be overcome, both in the OS and tool sets as well as the hardware, so I eventually sold my system and have been lurking around several Amiga forums for years. Right now AROS seems to have the most potential.
