Note that the base M1 Air is currently on sale for $899. It is a vastly more capable computer than the i3 one. I do not think the $100 savings is worth it.
I think the i3 Air would be worth it if it was priced around $500-600 and battery life, processing, and graphics were not all that important to the person buying it.
