I just bought a new apple laptop. At the checkout I was told that the power adapter is a distinct item that I need to buy.
This would make sense if the power supply were a commodity item like for a mobile phone. However Apple decided to require a custom magnetic plug and needs a 70w supply. You can’t argue that you are using standard components then require a custom one.
There is not even the option to buy a sensible setup where the adapter is a distance from the plug.
I don’t bother with the apple mouse, which has the charging point on the underside so the mouse cannot be used while charging.
