I'm pretty much set on getting a hackintosh towards the end of the transition period as an upgrade to my current Trashcan MP. Something based on components as compatible as possible (probably just straight up one of the tonymac 'golden builds'). The plan is to use that to get the most out of the OSX software licenses I have acquired over the decade.
Here's to hoping that there will still be some decent picks for upcoming AMD GPU's that perform well. Not liking what I hear about the 1st gen Navi in OSX, nor do I want funny firmware issues like fans full blast in sleep mode. And RX 580 would be a tad underwhelming to say the least.
I don't think I'll make the jump to ARM unless somehow it's way beyond Intel/AMD/Nvidia. The whole soldered-on, locked-down, gatekeeper-required-direction of the platform has been bugging me for a good few years now.
