I don't get it. I work at a university and I see a LOT of people with laptops... and I can only recall one Chromebook, ever. Mac laptops are extremely popular, both with students and with faculty - I'd guess it's about 50% of the laptops I see are Macs. Maybe it's different as we're a technical department (EE) that's right next to the CSE department - so those are the students and faculty I tend to see.
As a side note - a quarter or so of our faculty really like the Surface. iPads and Android tablets are neck in neck, but both are definitely in second place.
Not just you I go to one of the largest Universities in the US and I certainly see more Macs then I do HP or Dell and certainly Chromebook. Not saying that I do not ever see the others around campus but at least on our campus and from friends descriptions of their campus the Macbook is clear favorite.
