It's interesting times. I am interested in an M1X Mini, but at the same time, I'd rather use my Intel Mini for many more years to come. And if an Intel Mac Pro 2022 comes to fruition, I think the shift to ARM-specific software will be slower than initially planned (along with the pandemic and chip shortages).
I'm thinking I may have 4.5-5+ years from now before Intel Mac OS becomes more or less unsupported.
