[Trisquel-users] // , Does Trisquel work on the Dell XPS L512X or any of the 2015 MacBook Air Laptops?

  // , I want to see whether I can install Trisquel 7.0 LTS Belenos on either  
of these, the L512X or the MJVE2LL/A.

Has anyone had a go with these models, or models like them?
I know TriSquel is based on Debian, and Debian works on the Dell XPS L512X,  
but I don't know whether anyone has tried either of the above laptops out  
with those distributions without the non-free components.
