I forgot to list magsafe as one of those awesome things that was lost. I could take or leave the power indicator but it was kind of cool. It's such a no brainer that I'm surprised it's not been copied. Apple must have patented it too well.
It was a very special manufacturing procedure, something that is hard to copy without the special hardware.
And Apple bought all that supply. You couldn't get the production line to do it...
(IIRC, bit my memory may fail me on that. Please Google it, I would be interested in rereading it!)
I mean just show an error on the screen. It's not the end of the world.
