Times have changed. Macs are down to a pretty small percentage of Apple's revenues - what Apple needs is widespread uptake of macOS to promote the ecosystem of macOS + iOS.
"Apple knows bit from iOS and OSX that one of their defining advantages cones from their close ties of hardware and software. They won't give that away again."
Apple is using almost completely generic PC hardware at this point. See my other post regarding hardware.
"The drama around the new MBPs is all about price. No idea why they went so high but if they were more in line with with PC pricing there would be very little complaint."
Not at all. Much of the drama around the new MBPs was how anemic they look compared to other "pro" laptops. They don't even support 32 GB of RAM, much less 64. No ECC. No Xeons. No "pro" level graphics chips.
Apple is the largest and arguably richest company in the world. Surely it could do a much better job of serving the many market segments. One size does not fit all!
