Okay...?
Why don't you have one of those?
You think Apple would be better off following everyone else?
The opposite has worked pretty well in the past.
I'm simply saying Apple choosing to not include ethernet ports and optical drives in their computer does not mean the technology is considered legacy, as far as the rest of the world is concerned.
It may be considered legacy for Apple because they want to trim the fat and produce the thinnest laptops known to mankind. But that doesn't mean that they're not still heavily used in the rest of the world.
