I'm still on Mojave, but all my regularly used apps, including all my dev tools/services are all 64-bit, and while I realize several of those won't be ARM in the short term, I suspect eventually __and__ they're pretty lightweight apps (for example, Postman), so that they;ll be good for running under Rosetta.
I have time to figure out my few Winders™ needs, some things I've moved to Docker, some to cloud services, I'm definitely in a wait-and-see mode on a few things, but I can say, I'm mostly excited 🙂
I'm hoping this means an A13X/Z or A14X/Z powered Mini with a kickass GPU in the next 8-12 months 😀
