So what are you saying? That a lineup of computers that never used top of the line GPUs is starting to use integrated solutions since they've finally become good enough to address the low-mid performance range Apple usually aims for, and this is somehow indicative that high end, expensive GPUs are going the way of the floppy?
It's proof of nothing. Well, other than the fact integrated GPUs are now officially "good enough". People who bought high end GPUs beforehand will still be buying them the same they always have. There isn't an integrated GPU out there that can match them yet.
When serial ports and floppy drives went out of style, there was already a better solution in place to replace them. Floppies had disc burners, and serial ports had USB. Manufacturers kept them around for a bit because, yeah, backwards compatibility.
That's the point you're missing here. They were replaced because there was something better out. For now, integrated GPUs aren't better than discretes. They work for some people, but they don't work for all, and they certainly don't address every single need of the market. The only thing that's "switched" is the death of low end $50 GPUs. The high end is still very much alive and healthy (olol, but not in Mac World, watch me move that goalpost).
Where did I ask for a Mac Mini to have a discrete GPU? Hell, I'd be shocked if it used an Iris Pro.
