Yeah, yeah, I know, enough with the wacky USB devices, already! We can’t help it. We have an unhealthy fascination with this product category: coffee warmers, hands and feet warmers, ah…personal massagers, night lights — all things that are perfectly happy in an AC socket or battery-charged — somehow take on a shiny allure when powered by your computer’s USB port. The feeling that you’re getting the power for free — I guess that’s the attraction.
The latest USB-powered widget is an essential oil pot. Put your favorite fragrance in it and try to mask the fact that your cubicle stinks of day-old pizza, late-night coding sessions, and online dating desperation.
