Why should they provide a differetiated product line? Hyperion etc. haven't, Cloanto doesnt. OS4 is for PPC only, Aros is open source and can be ported to different archs but x86 is the main one.
And
when have Hyperion, Cloanto, or A-Eon been held up as exemplary niche computer businesses, exactly? Providing a differentiated product line could give C-USA the opportuntity to do something that they
don't: serve more than one segment of the market. There are people here who would be happy to run Linux with an emulator on an x86 box, and more power to them (and to C-USA, if they're just serving that need and not trying to promote themselves as the True Successor.) But there are also a lot of people who'd like to see something else that's closer to the original Amiga, and their options are woefully limited. If Barry is such a successful businessman, he might have the potential to see through some of these community projects to completion and make them available to
all the people who want them, not just the few that get their hands on developer prototypes and testing boards while waiting for the real thing to finally be available.
Or, you know, he could follow your example, shrug his shoulders, say "x86 wins, why bother, nothing good ever came of doing something different," and go with what everybody else does.
