Want to go green but don’t know where to continue apart from recycling tins and bottles while using less plastic bags? The USB Green Button is a foolish way to part with $12.95, as it touts to put your computer to sleep mode simply at the touch of a button. Granted, most modern machines these days can be programmed to run in various power schemes and modes, even shutting down the hard drives and display after a minute of inactivity, making us wonder why the USB Green Button is so late into the game. Perhaps it targets much older machines that do not have such modern features, who knows? Made from ABS plastic while glowing in green, this round shaped device is compatible with Mac, Windows Vista, XP, Millennium and 98(!) operating systems.
