Well, that's how business works. Apple clearly seems to have changed course, but it's tough to adjust heading on a ship like Apple.
As has been pointed out many a time in this thread and elsewhere, no one has forced you into buying Apple. If you've switched and it's working for you, that seems like an ideal outcome. Apple doesn't owe pros anything, and the opposite is very much true as well. It's business.
Far be it for Apple to listen to the people that don't buy their products, because of product shortcomings. I skipped my upgrade cycle, because the 6,1 didn't fit my needs, and used some of that money to build a linux box, that I also run virtual machines on.
Somewhere around here I started a tread about my virtual Mac Pro being better than a real one.
If the 7,1 offers what I need, I'll still buy one, as I prefer to use the macOS. Thing is, when the hell will that be?
Apple's too fat with iPhone profits to care much about the Mac Pro line, and it shows. More and more people on this board defect, and once they build the toolchain they need on another OS, they can be locked into it because of the costs of pro software. I fear those people won't come back, or won't come back until they need to update their software suite, making 7,1 sale less than stellar, and perhaps leading Apple to end the line.
I'm lucky, I built my software suite on open source, so I can run it on any platform, and the only thing it costs be to move back and forth is some time.
