classic amiga without ppc is underpowered overpriced crap.
060 is a 486 class processor, and without ppc graphics speed is comparable with 486 vlb.
Let's now be a bit realistic. PPC is not exactly available at budget prices either, and not exactly on par with the x86/x64 processors anyhow.
If you want to go for budget hardware, I would strongly argue that AmigaOs should be ported to mainstream hardware.
Decision to not suport 68k crap was very wise.
It could have been, if mainstream hardware had been selected. Which was exactly not what happened. I wouldn't call this a "wise" decision. There are actually two realistic markets: Either go for powerful mainstream hardware, which is certainly not PPC, or go for the vintage market, which is not PPC either.
After all, this doesn't sound so wise to me.
ppc is ofcourse fully compatybilne with 68k.
Did I miss something or are you living on another planet than I do?
