None of the two PPC computers out are "Amiga" computers. One just has the badging slapped on.
The A1 isn't just an Amiga because it's created by the continuation of the same company, you know? Considering that it runs AmigaOS (based on the orignal source code), I'd say that it's just as much an "Amiga" compared to the "Classic" line as a modern Mac is compared to the 68k Macs - just that there's been a period without any new developments. Of course, that doesn't make other solutions inferior in any way, but just different...
