I am aware that ARM is well-supported on Linux. However, the OP was asking about ARM laptops with at least half the performance of the M1 and long battery life.

I am aware that ARM is well-supported on Linux. However, the OP was asking about ARM laptops with at least half the performance of the M1 and long battery life. The 13-year old AC100 and Pinebook don't meet the ops' specs of half the performance of the M1 and great battery life. Nor would any of the other examples you list. The MNT Reform looks neat, but I doubt the performance and battery will meet OP's specs. Nonetheless, pretty neat. The Nintendo Switch isn't a laptop.
