I do at home for my laptop which I sometimes (not often but I do) "roam" with. I don't like the mains cable option and fear it might conflict with X10 (home automation) switches here and, the reliability of which does make me doubt and other mains cable systems.
Certainly though, I do favour "proper" wiring where possible and have wired access points for the laptop in my room and the living room - actually took the wire outside the house as the easiest means of achieving the latter.
