I've got the 13" MBA - I'm pretty impressed. My main computer is a beefy desktop gaming PC with an Intel i9 - but the MBA with M1 can do some of the tasks in a comparable time! The GPU is also impressive - better than any integrated GPU that I've tried before, and not that far behind the RX570 in my HTPC. I'm pleased that Apple is back to focusing on general computing after all those years focusing on mobile devices.

Edit: I meant to say RX570 not RX560. The M1 GPU is actually slightly faster than an RX560 see e.g. https://askgeek.io/en/gpus/vs/Apple_M1-gpu-vs-AMD_Radeon-RX-....
