It might be true, but I ask: What are the needs that the new Macbook satisfies and an Air doesn't? The only one that comes to my mind is a retina display, because both have similar portability, it has 1-3 hours less than the Air (depending of 11" or 13") and you can't even do a decent videoconference (480p really?). What I mean is: what's exactly the point of it, that can't be satisfied with an Air appart from the screen? To me this new Macbook is more about design and "hey, I have the thinnest laptop ever, in gold!" rather than focussed on any functionality or use. Just my opinion tho.
That's it, original MBA had low-end cpu and gpu, and look at it now. That's why I wouldn't go with the new MB as an early adopter. I bet it will finally end with i5 when Skylake comes with much reduced consumtion, or with Cannonlake in 3-4 years (similar to what happened with Air), and 1 more port unless wireless charging comes soon. It's clear they didn't make their best with nMB, since they need to have stuff to upgrade next year
