This company sells freedom-compatible hardware with Trisquel pre-installed. Thought it would be interesting to share.
Do you know of any other?
Los Alamos Computers offers Trisquel and gNewSense, among others: http://laclinux.com/gnu/GNU_Linux_Computers
ZaReason used to do this, but they no longer offer Trisquel as an option on any of their computers. They claim on their forums that some of their computers will work with Trisquel while others require non-free drivers.
