World's Dumbest USB Gadgets

Thermaltake DeskCool
Though not yet available on the market, this knick-knack was recently unveiled by a company called Nuventix. Kind of like a cold version of the bathroom hand-dryer, the DeskCool is aimed at gamers who get sweaty palms from intense gaming sessions (and from being in the vicinity of the opposite sex). As we all know, a moist mouse hand is killer on you precision. What saddens us the most about the DeskCool is that it's a pretty dumb application of a potentially great technology. The unit apparently generates airflow from a vibrating membrane on the inside -- there's no fan. We'd rather see this system being used in computers, video-game consoles and everything else that requires a noisy internal fan.
