The H is my second favorite camera platform. In the H4D, it is very mature and the true focus feature is really incredible. My problem with the H (which may be a strength to other shooters) is the lens system.
Fuji and Hasselblad haven't really taken the quality of the out-of-focus areas (bokeh) seriously enough, in my opinion. Too often, I have seen rough bokeh from these lenses (unless shot wide open)--but this may not be a significant issue for studio work. They have optimized the lenses for studio shooting distances (rather than infinity for nature photographers).
But lenses aside, it is a wonderful system, and well thought out.
