I have said this many times before and I will say it again. Apart from the
whole Freedom aspect, Trisquel is one of the easiest and most stable
operating systems I have ever used.
I do think that part of this is purely down to the Free software nature of
the product. Without a single proprietary piece in it, there is no hidden
code that can intentional/unintentionally to mess with any other part. No
bugs that cannot be crushed.
My install of t& is probably only a little bit older than yours but I'm in
the same boat of not having any issues.
