Working on a platform I have no emotional attachment to.
The PPC systems are neither current nor retro, so there's not much interest from people like myself.
To me it's much more interesting to tweak old systems with some sort of nostalgia.
For those who want a PPC system, more power to them, I just wish that the people with the license to the OS cared about the same market I do, which is 68k.
I don't mind if it is 68k, PPC or... i486

. IMO problem (I expressed this once of twice

) is not a lack of hardware. There is like few billion PC that can run AmigaOS3.1 and/or with 1000+ MIPS and... who cares?
Speed will not bring quality software. I tried AmigaOS4.1 on my PC and... I turned it on last time about 6 months ago. There is nothing I can do using AmigaOS. OK. I could post on this forum

.
I have installed UAE (both versions) on PC and... basically there is no software I would/could use today, also system is WAAAAAAAY outdated.
Investing time and money to "develop" super outdated PPC motherboards that can run AmigaOS4.1 is IMO waste of money and there is NOTHING "special and Amiga like" in this new motherboards.
At this point of time we need... web browser, office package (must be compatible with MS Office). THEN we can start actually working on AmigaOS and even replace it in case of SOME of us, that don't need specific software.
At this point we need system and software that in some way will introduce something NEW and interesting to "market". If not my super old A1200 will be fine...
Considering that today people are sick and tired of MS collecting data from their keyboards... Linux "sucks" etc. and MacOS is good for "...". AmigaOS could be viable option.
Focus on development of AmigaOS and software, what hardware it will run? It will be a problem of future.
