XYZ Computing has posted a review on the Razer Armadillo

Razer calls the Armadillo the "ultimate cable management system". This is a tool used in conjunction with a mouse in order to prevent accidental mouse movements due to the cable. Razer's mice use extra long cables which can easily get caught on items on or behind your desk so the obvious solution is to get some slack on the desk and then put a weight over the cable so the length which is hanging off of the desk does on interfere with the movements of these ultra sensitive mice. Normally this is a speaker or some duct tape, but Razer has taken the next step.
