My next home will have multiple fiber pairs to high-use rooms, plus 
convenience wireless.  I don't intend to pull copper through the walls.

I plan to put switches in rooms that need multi-drop and have at least 
one pair of fiber for high-speed access for a server, NAS, or cluster 
leading back to the wiring closet and patch panel.

With a glass infrastructure you can support a lot of technologies.
