The very delicate TouchONE
Korean company Virtual Lab System has a more elegant alternative to the on-off switch on your PC. The TouchONE ("Don't push, just touch!") is a silver pendant-looking device containing a touch sensor that sits on the flat surface of your choice and glows blue when touched. More than that, it also turns your PC on and off. The only snag, according to the folks at Akiba PC Hotline, is that the sensor is way too responsive, meaning that you can end up turning on your PC simply by trying to pick it up and move it. Fortunately, turning it off again requires you to hold a finger against the sensor for a few seconds, reducing the risk of unconsummated frag sessions. In any case, caveat emptor, as the Romans were fond of saying about their peripherals.
