If you're a fan of long fingernails you've probably already developed special techniques for using touchscreen devices. But Sri Vellanki, the creator of a fingertip stylus called Tech Tips, feels women shouldn't be limited to what technology they can use because of their fashion choices. So she's developed a touchscreen-friendly fingernail that works like a high-precision stylus. Available sometime in May in packs of up to six for about $10, the Nano Nails hide a tiny capacitive tip under the index fingernail that can be detected by a touchscreen just like a fingertip. It's all but invisibile unless you're looking for it. They save you from having to carry a separate stylus, and since they're glued to your finger they're always at the ready. There is apparently a slight learning curve as you get used to using the proper angle for the capacitive tip to make contact with the display. Read the full story at Gizmodo.
