They haven't just said it in a keynote, they have been showing us by doing by not updating their product lines all that well lately. Go look at the buyers guide!
I'm not throwing my Mac away, I'm upgrading and migrating away from it. Current daily driver is a 13" rMBP (Late 2013). Has served its purpose, but less than three years later, it can't drive a 4K display properly (@ 60 hz), the graphics performance sucked from the second I first turned it on and really this machine has always felt laggy and still does to this day. I loaded it down when I bought it thinking I would be happy with it for next next 5-6 years, but have ended up disappointed because of the aforementioned. Take this experience, plus the kind of shenanigans that the buyers guide exposes, Tim Cook's Mac-dignifing "vision" quote and the expiration of my machine's AppleCare warranty and... I think I'm at a logical point to step away from the Mac.
Sounds like
@Osty wasn't planning on throwing anything away at all, but just move their primary usage away from the Mac and to the iPad. Exactly what Tim Cook wants.
I don't really see a future for the Mac at this point. Even as a niche product. It really looks to me like the sun is setting on at least half of the Mac lineup. Few things that might survive this culling are a reduced lineup of a single iMac config, the MacBook one and 15" MacBook Pro.
So for me, the best thing to do is move on to a different computing platform and keep an iPad around to, again, be my window into the Apple world. Eventually this same reality is gonna hit more and more people here in our corner of the web. iPad Pro with a physical keyboard isn't all that bad if you can get your work/tasks completed on a system that restricted. Windows 10 really isn't all that bad. Linux is a pretty darn good UNIX-like OS.
But by all means, keep fighting the people who have control over the future of the Mac. See where it gets you in two or three more years of this.
