The Apple Page -- M1 Vs M2

Link here.

Bottom line:

• if you already have an M1, don't upgrade
• if you don't have an M1 MacBook Air, you will do just fine with buying the M1 MacBook Air and not the M2
• but if you want to spend the money, and I don't know why you would, get the M2

In other words: for 98% of the population, the M1 MacBook Air is the better buy.
