Gadgets : Elecom's disc data crusher

I can't decide if this machine is utterly useless or...just a waste of space and money? This new product from Elecom Japan claims it can make any CD/DVD-ROM disc unreadable by putting scratches on it within seconds. It's powered via USB and is being marketed as an indispensable security feature for your office.

I'll let you decide for yourself if you want to buy one for 3,150 yen at the end of the month. Me? I'm just gonna continue using spent discs for stress release by snapping them in half and writing profanity on them with a Sharpie.
