Here is a video of the latest version of e17 (which I'm using on all my
computers including on the Neo Freerunner which runs the mobile version of
this on Debian) which looks much better in my opinion:

e17 would also work well if Trisquel wants to port itself to tablets in the
future as e17 also has a "mobile" preset when setting it up (as I did on the
Freerunner). The fact that it works reasonably fast on the Freerunner, which
has a very weak processor without any hardware accelerated graphics, shows
that it can work on very old computers with very poor graphics cards as well.
