Summary: I wanted the smallest switch I could find for travelling when I need to tap into the cat5 of an existing desktop. What can you say about a switch? It works. My ideal would have been even smaller (perhaps only 2 ports - 1 in & 1 out and an ethernet to usb converter for the laptop - all powered from the usb connection)but I don't think that product exists yet. As far as I could find, this is the closest I was able to find to a mini switch.
