I thought *you* were preparing computers for "average folks". Now, if your
grandma is the one concerned, let her talk to us. I am sure she is not as
dumb as you depict her.
All reasonably recent Intel processors have a graphical chipset. Anyway, many
computers have a video card on top of the motherboard for better performances
(on proprietary systems). This card can be removed and not substituted by
anything.
If you go for installing a Linux kernel with blobs (I would never recommend
that) but do not want to mess with the repositories for APT, then that kernel
would never be updated. On the contrary, the kernel that Trisquel ships
receives (security) updates.
