Hygienic Touchscreen Tool

Never touch a skeevy store screen again with this brilliant micro-stylus from KeySmart. The diminutive size won't weigh down your keychain, and you'll have it at the ready when you need to swap in a pinch-hitter for your index finger. (Psst - it's also handy when you're wearing gloves that impede your swiping ability.) Cost: $8.
