one thing I think people overlook with nTB vs TB 13"
is lack of the side vents which people complain is sharp feeling in transit
not photographed well because you'd have to see it from the proper angle but
This was something I realized when I played sound out of the internal speakers. You'll distinctly hear the sound coming out of the sides / bottom of the TB model, while on the nTB it comes straight up out of the speaker grilles.
