I pretty much said my piece in the other thread, but just to reiterate:
C-USA, thus far, has billed their products as somehow being a successor to the C64 and Amiga. And no, despite BigBenAussie's protestations to the contrary, it's not just "modern tech in retro cases" - the whole of their website is designed around reminding people how cool the C64 and Amiga were and suggesting that this is somehow related.
Yet not only have they not even begun to approach that level of innovation and quality engineering, they're not even trying. The full extent of their creative efforts has been to create a reproduction C64 case for one particular model of generic x86 PC, and pick some stock cases that look sort of like the desktop Amigas for some others. It is plainly obvious that the only thing they're interested in is flogging the brand they scavenged for some extra money.
Shipping with AROS would be an interesting event, but it wouldn't change the fact that they're sticking generic x86 PCs (are they even manufacturing the innards?) in slightly custom cases and then trying to pass it off as the legitimate heir to the crown.
Back in the day Commodore brought an unprecedented combination of computing power, multimedia capabilities, and low prices into the home-computer market with the C64, then did it again with the Amiga and added a solidly-engineered OS into the bargain. C-USA has innovated nothing, and while its systems, going by the listed specs, are reasonably powerful, I sincerely doubt they'll be more powerful than the competition for less money, as both the C64 (against the Apple IIe) and the Amiga (against the Macintosh) were.
But that is, admittedly, a difficult trick to pull off these days. I wouldn't be so bothered by it if they were either A. trying at all to create something new, or B. not dressing up the status quo in Commodore drag.
