I have my new M1 Mac mini for three days now. Many hours of WFH with it. Love this machine! Fast as a lightning, extremely snappy.
Yes, there is some odd behavior here and there. But nothing that affects the general impression. Rather some minor quirks that will mostly be ironed out in the next software releases (by Apple as well as by third parties).
The previous machine was a 13“ MBP early 2015 (it is still here). Earlier this year, I tried a 2020 Intel MBP 13“ but that gave me no leap forward so I returned it, especially the snappiness did not improve significantly. But now, when I press keys, do clicks and scroll, there is immediate action, zero latency. Great!
