Its drawback is poor performance but it’s ok for basic use — surfing the web, typing docs and notes. I almost got one in 2015 if I could code in it but I tested it and it was way too sluggish.
TBH I'm surprised apple didn't make the 12 macbook M1. The air is already fanless and the M1 chip is only 10W. I guess they really wanted to impress everyone with battery life numbers.
However a 12 inch MacBook M1 would be incredible.
