The problem is - our users aren't interested in being educated, they are
interested in making their stuff work. Taking the high road benefits
nobody (yeah, I know that this is the story of the legacy PC world, but
its the world we live in).

This won't come as a surprise to anybody, but we are lagging years behind
the other architectures. There are already very good free and open
source boot monitors for many of the other architectures. I view the
coreboot effort not as creating something new and magical, but rather
as dragging the x86 into modern times to catchup with its cousins that
long ago passed it in terms of cluefulness. I hate the idea of spending
valuable cycles thinking about other architectures when we're still so
far away from making our primary one work. Just my opinion.
