Something tells me Carsten will not like to ditch X ;-)

If I understood his point, he is saying that everywhere he looks he sees
bloat, and that he can imagine to put some of these apps on a serious
diet and / or move them out of X init to bite into that 15s he sees
going that way.  And indeed a settings-*daemon* doesn't need pango, etc.

Sounds good!
