When I remodeled my teenage son's bedroom, I knew he was a computer nut, so I put in a double duplex for that. Didn't help. He added a surge strip (for protection)and now all four spots are used as well as having a full surge strip.

As I posted in another thread on this subject, a duplex surge protected receptacle lists for about $50.00, and then you only get 2 outlets. A reasonable surge strip runs about $30 and you get 6-7 outlets.

The UPS and plugmold solution sounds the best to me.
