From Kikkerland comes Electroman, a 4-outlet extension cord with room for the largest of 3-prong adapters. While snooping around the Atlanta Retail Gift Show last week I also saw that they are now offering a USB Hubman as well.
(I scored a whole catalog from the Kikkerland booth but somehow managed to lose it before I got home. Needless to say, all the goodies are on their web site so check it out!)
