I knew it was only a matter of time until some developer figured out a way to turn the big trackpad on the MacBooks into a little tablet. The folks at Ten One Design have stepped up to the plate with Inklet, a program that does quite a bit. Inklet accepts input from the fingertip, but adds even more functionality when used with the company’s Pogo Sketch ($14.95) stylus. The Pogo Sketch is designed to add stylus control over touchscreens, and that includes the MacBook trackpad.
While Inklet ($24.95) is designed to allow drawing into programs that accept such input, it also leverages the handwriting recognition built into OS X to convert handwritten input into text. The program has palm rejection to prevent inadvertent input when the palm is resting on the trackpad. To appreciate what Inklet can do, have a look at this video:
