@Hammer:
"Don't hold back" is an idiomatic expression. I am guessing English is not your first language? In any case, don't fret it was not important.
re: legacy:
Sorry, just don't agree. Legacy support has been the biggest bane of Windows. I am well aware of MS' position, too. I just don't agree. As for x86, x86 != windows. Though X86 too has suffered because it is just a 1970s CPU on speed. So, yes, I think I can paint it as a "negative point" thankyou!
re: "superior" as I said in my post, that can depend on what you want. Where another platform delivers better performance in a given area, or features that are better suited to a certain market, it will establish itself as the dominant player in that niche. The ones that die are those who never had a niche, or else did not properly cultivate it once they gained it... Amiga anyone? :¬)
re: OpenGL: As Matt says, Warp3d is indeed OGL. I have not paid full attention to every aspect of AROS, my current involvement is in a very specific area for now. Also I was part of a discussion about whether or not full OpenGL support ought to be present.
re: DirectX: It does the job MS hoped - it is a high performance, proprietary set of libraries for multimedia applications. These days it covers every aspect of gaming, it started as some hardware independent (well, vendor independent) drivers for sound cards and video cards, combined with a standardized API for 2D (later 3D as well) graphics and sound&music. I happen to think its usefulness is rapidly waning, given the high quality vendor supplied drivers for the Windows platform which don't specifically target games.
