Perhaps the Firefox OS terminals in the market are not the best, but there is definitely a niche. If the underlying idea is sound then they have a chance: running HTML5 apps on bare metal saves resources, since there is no OS to manage, and terminals can be much cheaper.
Personally I doubt it is a good idea. Look at how Android has taken the market by storm with a weird stack made of Linux + a custom Java interpretation layer, both quite wasty in resources. Apparently bare metal is not so bare these days. But the strategy is sound: it remains to be seen if a good implementation can storm the market from the bottom up, as such revolutions usually happen.
