Here's an opinion: we all love to argue and it doesn't matter what anyone else says because the joy is in the arguing. And that is particularly true when it comes to the nMP because it is clearly a niche business for Apple and no matter how much love Apple seemed to show for it when it came out, it now seems like a bastard stepchild, with the red hair and big ears, not having anything against either, but until a person grows into them, they seem awkward. In the case of the nMP, the lack of flexibility, the fact that there have been improvements in graphics necessitated by the move to UHD, and the need for even larger files to accommodate UHD, which all seem to be beyond nMP's capability at this time, and the lack of any roadmap from Apple, which it never does anyway, leads everyone to speculation and concern, and the only way we're going to find out is just wait, just wait, and who wants to do that?
I'm glad that I don't need my cMP for professional purposes, because I know that it's old and slow compared to current systems, and it can't process UHD in its current configuration, but then I don't need it to, and my only skin in this game is that I love Apple products and I hate it when they seem to do something less than smart, and then explain it in a way that doesn't leave them any avenue to fix it without admitting they screwed up, because no likes to do that. So the question is will they? Admit they screwed up? WWSD? He would fix it and suggest that's what he had in mind all along. Time to fix the nMP.
