I completely agree that my needs may not be the needs of everyone and actually, when we're talking about Apple, they tend to be changing ways of usage rather than following them.

Another perspective I've seen recently about this is that this new Macbook will probably make people change their habit towards something traditionally only for smartphones: you'll see people keep their computer untethered for the larger part of the day, and only plug it for energy during the night. So, basically, mobile first instead of plugged first. You then have a port constantly available for whatever you want to plug on the go.
