With the MacBook One, Apple reduced that to cables coming out of one side only.Need to see exactly how big those bezels are, and the overall laptop footprint, but I like it better than the impractical Macbook. Ports on the back are better than ports on the sides, imo. Whenever I used my MBAir on a desk, I used to hate having the wires coming out the sides whilst using a mouse.
And with a laptop that thin, the only place to put ports are at the back because that is the only place where the combined thickness isn't split between the bottom part and the screen. And that also only works if the hinge is move forward a bit such that there is space behind the hinge for a full-height bar with ports. Note that Apple's G3 Powerbooks also had all ports at the back (thickness or lack of it wasn't the reason back then, rather that the PowerBook G3 had removable bays on both sides that could take a battery module, optical drive, ZIP drive or even second HDD).
I personally find ports at the sides easier to reach, in particular for stuff that gets removed frequently. Many people criticise that the iMacs have their ports on the back. So there are definitely downsides to either solution.
