Website designer and illustrator, Sandra Trainor, reviews Inkling for About.com readers. She finds Inkling to be "freeing" and likes the concept of being able to create preliminary sketches on paper and refining them later on the computer.
The Inkling pen allows you to create digital sketches while working on standard paper or in a sketchbook. It's designed for the beginning stages of a creative project, when laying out new concepts. Sketches can later be transferred to your computer for refinement.
The pen has a pressure-sensitive ballpoint tip with a sensor that works with a wireless receiver. The receiver clips to the edge of your paper or sketchbook to capture a likeness of the sketch digitally, and can store hundreds of sketches before transferring them into your computer.
