The Thylus is an interesting alternative to using your stylus. The Thylus lets you use your thumb instead. Yes, your thumb! Most thumbs are wide and data entry is therefore clumsy. But the Thylus takes the thumb and turns it into a stylus with a pinpoint for data entry. Essentially, you put the Thylus on your thumb and it will let you precisely control screen input thanks to its nib. An adjustable beaded ring allows it to be sized for different size thumbs.
It comes with a convenient docking station that can be affixed to the device so that the Thylus travels with it.
The Thylus is available for $6 USD plus $2.00 USD shipping directly from Thylus Inc.
