Did you ever think your trackpad could be something more? Inklet allows your trackpad to emulate a pen tablet. When you're using a Pogo Sketch, the trackpad even becomes pressure sensitive. - The full tablet experience: Moving your Pogo Sketch lightly around the trackpad will allow the cursor to hover without inking. Increase pressure to draw; heavier pressure will result in a thicker stroke. - Handwriting recognition: Inklet works with the handwriting recognition built into OS X. Use your trackpad to jot notes or doodle. - Advanced palm rejection: Inklet includes an advanced algorithm to detect unwanted trackpad touches. This means you don't have to worry about accidentally resting your palm on the trackpad as you draw.
They refund you your money fast and it looks keen on your Mac but is all, maybe it works with other software programs which are a lot more expensive.
Cons
Lots of bugs.
Summary
The product information state that you can use Inklet with Adobe Photoshop Elements, this is absolutely not so, you only get a gray page in which one cannot write even one letter.
An other problem is that even while not using the program it seems to be on "Stand By" and a while typing anything all of a sudden it pops unexpectedly up which is quite disturbing and this not even with the advised "Hot Keys".
