That's a similar idea to what I use. Mine is simple in 'stick' form with on/of switches for each tap.
I'm lucky in that all my transformers for the chargers will fit side by side on the strip.
They are selling something here that designed to hold all the ugly transformer boxes in one closed and covered container, with only the electric cords coming out to be seen. I was thinking of getting one for my external hard drive transformers (I use five external drives, plus sound system transformer, etc) just to clean up the look under my computer desk.
