Back in the day, simply owning a personal digital assistant was the expressway to geek cred – you whipped out that Newton, and folks knew you were someone to contend with. But now, with everyone from high-school students to presidential candidates slinging Palm Pilots, the true nerd needs a little something extra – such as an adjustable plastic finger nipple, say. The three-for-$4.95 Stinger Stylus, from Orbit Industries (973/324-9896,
), lets you tap away on your PDA with a small stylus that attaches to your finger. The Stinger not only eases hand strain, stores effortlessly, and comes in a variety of colors, but also sets you apart as the biggest geek in the room.
