12-inch macbook is certainly no question on the weight.

but it lacks of hardware and power still comparing to macbook pro or even the macbook air now.
single usb-c port and not even thunderbot 3 capable is a bummer.
with no touch-id also it makes it less convenient than macbook air or macbook pro.
512gb please. u will regret if you get 256gb model soon.
consider that even an iphone now has easily 256gb or 512gb. u cannot even backup your iphone on ur macbook without additional storage with configuration nee

dun cheap out on storage especially a macbook can easily use for 5 to 7 years or even longer.
