I like it.
Maybe I would have emphasized the words freedom, privacy and market-freedom,
in bold or something. Same for Trisquel GNU/Linux. These are the selling
points.
Also, maybe borrowing from comparative advertising would help rive the point
faster and harder. In most people's minds, let's say there's Ubuntu, Windows
10's statement about freedom and Privacy in their licence, etc.
It shouldn't be legally risky, just pasting parts of their licence to drive
home what makes Trisquel different and better.
But yeah, it's a brochure, not a book. Probably not enough space.
AS for the image choices on the first page, it essentially features
GDM/Login, GIMP, The programs-rich repo, and file-managing and video.
It can be crowded fast, but some "impressive" software to feature could be
Blender, LMMS, Krita, something code-related (an IDE or a text-editor), a
browser, email client, LibreOffice (reusing ideas from your text).
That's probably too much, but it could give a fuller, more striking picture.
Maybe the desktops organised in a grid showing these softwares could be an
option, provided it's readable.
Last but not least, "Enjoy Computing. Enjoy Privacy. Enjoy Freedom." I'd add
privacy as an important feature that could motivate people. I know it worked
for me. Or maybe "Regain control of your computing. Enjoy Privacy. Enjoy
Freedom." Yeah, too long.
Anyway, just a few remarks.
