This was just launched today: Improv

75$ Dev kit which might be freedom friendly. At least they say they aim for 100% freedom friendliness but admit that it is not always possible. It's not clear if Improv is 100% free but should be quite close at least. they say all the drivers and firmware should be free and you can also install Debian or any other distro on it so why not Trisquel?
