Great discussion, and thanks to Dan especially for the detailed speculation.
Being a Mac user has always been tough. I first crossed paths with Macs in 1987 (the Classic), though I didn't actually get hands on one myself until grad school about 1991. I was a traditional darkroom guy from the mid-'70s and computers to me were both uninteresting math machines and a looming threat to traditional photography.
In the '90s Apple almost died and Mac users were in the minority, but the OS of the time (as scary as this seems now) was always better than the Windows alternative. My first computer purchase in 1996 was a PowerMac 7300 (cost me thousands, eventually sold years later for $10...).
Fast forward to the present where most everyone has an Apple-logo'd product on their desk or in their pocket, and it's a new day. What hasn't changed is Apple's elitism and high prices, which seem to be the cost of admission to a world where computers don't feel like computers but more like seamless, well-oiled digital experiences.
On the one hand you have macOS which free is and a joy to use most of the time, and on the other hand the over-priced/under-spec'ed hardware needed to run it. We here are pretty much in agreement that the upcoming announcements won't change this a bit.
Someone on page 1 of this thread mentioned Hackintosh. That avenue seems to be the obvious (though somewhat controversial) middle ground solution for those who love macOS but can't justify or swing the cost of ownership of actual Apple hardware. And it is Apple itself which created the need for this genre, to be populated by determined users that have never been properly served by the mothership.
Thankfully there are "options" (Windows 10 and Linux), though many (such as myself) prefer macOS. I'm familiar with all three OS's; I have a 2011-build triple-boot i7 Hackintosh tinker machine running Mojave latest, Win10 latest and Deepen Linux latest. I'm writing from a general use MacBook Air right now because typing isn't taxing the GPU, ha!
I work in higher-ed IT and have access to recent model SSD iMacs in the office, and I support over 400 Macs of various vintages (including about 75 Mac Pro cylinders). But if I had to spend my own money for a newer, more current higher-end machine for home, the options would include serious consideration of the Hackintosh route, followed by a recent-model used Mac (always let someone else pay retail first, like with a car) and finally, a home-built Windows PC (he says holding his nose).
