No matter how much we love our touch screen devices, sometimes a fat finger (mine, not yours) just does not allow for fine enough control. While the problem can usually be solved by zooming the content at hand, that is not always possible. The end result can be frustrating. But iDigitip may help with those times.
iDigitip is a small conductive fingertip covering that gives you a finer point with which to do your screen touching. The small point allows the user to have greater control, and it looks like it would make an on-screen keyboard faster to navigate. iDigitip comes in a pack of two for $20, and you can find out more about them on their website.
