The techies at Adafruit Industries, an electronics company based in New York City, are taking the battle between Mac and PC to a whole new level with the release of the iNecklace. The new product is an aluminum pendant in the form of a Mac On/Off button. Each necklace includes a mini circuit board to make the charm pulsate with a bright white glow, like the light on a hibernating laptop. The $75 iNecklace has no operational function other than brightening the day of the Mac-lover who wears it. Adafruit launched the necklace as the first product in a new line of wearable electronics. Oversized eyeglasses and argyle beware — a new trend in hipster fashion has arrived.
