Fine, cognitive dissonance is the first step to overcome a false believe. You have to unlearn everything you think you know about PCs. Because your predisposition is misleading you in your continuously failed afford to understand Macs. If Apple stops to support a technology, it practically ceases to exist. You can either accept the new reality or switch to another platform. What you can't do is to complain about what people want. Peoples opinions don't count as long they are not working at Apple.
You know, people make jokes about Apple fans being cult like, but I usually take it as an over exaggeration. Yeah, I do find that some people are a little too attached to the brand, but it's nothing too out of the ordinary. You'll find Android and Microsoft people who do it, too.
...and then someone pops in, and things get taken to a whole new level. Seriously, man. That whole post reads like Moonie propaganda. It's profoundly creepy.
But anyway, to get on topic. Where has Apple abandoned dedicated GPUs? In the Mac Pro? Nope. It's got two of them. The iMacs? Not there either. They've got Geforces in them. The MBAs never had them. The Mac Mini had one the previous generation, but it only barely qualified as such. The 15" Macbook Pro is the only place where it's missing, and you can still get it in the high end offering.
So one difference that's only seen among one model is hardly any evidence that we're seeing the start of a trend. If the next gen iMacs only come with Broadwell integrated GPUs, then you might have some slight point. But for now? No. You have nothing.
And even if they do, GPUs aren't going anywhere elsewhere. It's not like Apple has ever had a history of using strong, top of the line GPUs anyway. Yet despite that, we haven't seen the rest of the industry top out at mid-line mobile graphics cards. They're aimed mostly at a market Apple hasn't played in for years and years now.
