I'd recommend Lenovo laptops. I have a Thinkpad T460s, which is awesome. If you really want the tablet/laptop hybrid, maybe a Thinkpad X1 Yoga, or something from the 'regular' Yoga series will work for you. Yoga-series laptops start at around $500, whereas the premium X1 Yoga starts at something like $1.400 I believe.
Edit: Linux support on Lenovo laptops is pretty good overall, and if you're a Windows person, they ship with that by default. If you're a student, they offer discounts as well, I believe. I got mine from a local seller without an OS and put Linux on it.
