Well, it is an interesting question. Yes, Atom and Geode are more expensive
than ARM, for whatever reasons. But an industrial board is about 1000 EUR
anyway. The situation is same it was with workstations before PCs broke
through.

Why a hobbyist would even look at Ravenscar?

IMO, a hobbyist if not obsessed with systems programming, wants full Ada
and a "normal" OS. This is quite possible to have today. And this is where
Ada shines, because you can develop and test on a PC and then just
recompile the code for the embedded target without any changes. At least
this is the way we do it.
